MAU Data Transfer Cap for multiplayer after May 2022

The official document below stated that “MAU Data Transfer Cap will be 50MB per MAU per Manth per app after May 2022”.

In this case, does it mean that “the total amount of data sent and received by one person in one app per month must not exceed 50MB”? What happens if it is exceeded?

Regarding the 50MB data limit, I would like to ask about the difference between the limit for each app after May and the limit for each session before May.

I apologize for the inconvenience, but thank you for your cooperation.
