       Form 6-K Submitted March 7, 2023

       General

   1.                                                   We note your response
to prior comment one. It appears that spend, a non-IFRS revenue
                                                        measure, changes the
recognition and measurement principles required to be applied in
                                                        accordance with IFRS
and would therefore be considered individually tailored. In this
                                                        regard, we note that
presenting a non-IFRS measure of revenue that deducts transaction
                                                        costs as if the company
acted as an agent in the transaction, when gross presentation as a
                                                        principal is required
by IFRS would violate Rule 100(b) of Regulation G. Please revise to
                                                        remove CTV spend and
PMP spend from your Form 6-K. Also, please refer to your
                                                        response to comment
number 7 in your letter dated May 24, 2021 regarding presentation
                                                        of net revenue.
