There are big changes in 0.22 with how ads and consent is managed, at least for users subject to the GDPR.

Firstly a simple change: interstitial video ads have been removed. These previously could appear at the end of each game, but they will no longer.

The bigger change is the introduction of Google’s User Messaging Platform to manage consent. This will combine the previous separate dialogs that would appear about consent for analytics and consent for displaying ads into a single flow.

There are advantages and disadvantages to this, which I’ve expanded on over on my personal blog.
