Description

Are FCM messages encrypted? Could MicroG ever offer end-to-end encryption or does it depend on each app's FCM implementation?
And can we monitor the message contents?
I'm not too fond of the idea of unencrypted messages going through Google's servers, so I'd at least like to know if/which apps send sensitive data so I can deny them FCM access 🤔
