   1.                                                   We note your response
to prior comment 3 as it relates to the definition of unique users.
                                                        Please address the
                                                            Explain your
reference to users visiting your site. In this regard, tell us whether you
                                                            are referring to
publisher or third-party sites as opposed to the company-owned sites,
                                                            and if so, revise
to clarify as such.
                                                            Explain further why
a monthly user measure would vary hourly.
                                                            If this metric
fluctuates significantly from period to period, address why you believe
                                                            it is appropriate
to disclose an approximate number of unique users at any given time

              if that is not reflective of other periods.
                Tell us how you calculate and validate the number of unique
users disclosed.
                Revise to address how you track or count "unduplicated"
                Disclose the period represented in your current disclosures.
2.       We note your revised disclosures in response to prior comment 1.
Please tell us why you
         are highlighting the growth in CTV advertising revenue, which
comprises only
         approximately 17% of your total IFRS revenue for fiscal 2020. In this
regard, you state in
         your response to prior comment 4 that both CTV and Video revenue are
the core areas of
         growth for the company. Also, explain to us the relevance of your
discussion regarding
         CTV revenue growth in six month increments. Please revise, as
3.       We note your revised disclosures in response to prior comment 7.
Wherever you discuss
         Adjusted EBITDA or adjusted EBITDA margin, please further revise to
discuss the
         comparable IFRS measure before any discussion of the non-IFRS measure
and ensure you
         include the IFRS measure for all periods in which you present the
non-IFRS measure. For
         example, you discuss the increase in Adjusted EBITDA on a six-month
and full-year basis
         but do not present a comparable discussion on an IFRS basis and you do
not disclose total
         comprehensive income for each period in which you disclose the
non-IFRS measure.
         Also, you disclose Adjusted EBITDA margin before you disclose net
profit margin.
         Please revise your disclosures throughout the filing.

4.       We note that you removed the subtotal of gross profit from the face of
your consolidated
         statements of operations in response to prior comment 15. However, we
further note that
         you continue to present gross profit margin and gross profit
information in the forepart of
         the filing. These measures as currently presented exclude amortization
and depreciation
         and therefore are non-IFRS measures. Please tell us the amount of
amortization and
         depreciation excluded from gross profit for each period presented. To
the extent you
         continue to disclose gross profit or gross profit margin, you should
clearly label
         them as non-IFRS measures, provide a reconciliation to the most
comparable IFRS
         measure of gross profit, which includes depreciation and amortization
in cost of revenue,
         and include all related required non-IFRS disclosures.

5.       We have evaluated your response to prior comment 5 and while we are
still considering
         your revenue recognition policy, we continue to believe that by
presenting programmatic
         revenue and cost of revenue for fiscal 2019 on a net basis exclusive
of media costs, and
         performance revenue for both fiscal 2019 and 2020 on a net basis
exclusive of traffic
         acquisition costs, you have substituted an individually tailored
revenue recognition
         principle for IFRS revenue and expenses. Please remove these measures
from your non-
         IFRS disclosures. Similarly, any measures that are presented on a
non-IFRS basis, such as
         net revenue, net revenue growth rate, percentage of video revenue, net
revenue retention

6.       We note your revised reconciliation of Adjusted EBITDA in response to
prior comment
         6. Please further revise to remove the subtotals of "profit for the
year" and "profit (loss)
         from operations" from your reconciliation.
7.       We note your discussion regarding changes in your various non-IFRS
measures beginning
         on page 61. Any discussion of non-IFRS results should not be presented
with greater
         prominence than your IFRS results of operations discussion. Please
revise so that your
         IFRS results of operations discussion precedes any non-IFRS
discussion. Refer to
         Question 102.10 of the non-GAAP C&DIs.
