All of the sudden I saw that our app had a new notification channel named "AdMob Offline Notifications".
We do use AdMob, so I assume it's created by Google's library, but I can't find any documentation on it. I'm wondering on what that channel is used for, and if it's possible to not have it at all.
The channel is created as soon as the app is started the first time. The id of it is offline_notification_channel
and its importance is set to low (no vibration, no sound).
I did manage to find others wondering about the same at https://groups.google.com/g/google-admob-ads-sdk/search?q=%22admob%20offline%20notifications%22 , but no answers so far.
