These notifications are bundled together for some reason. So if I want to be notified when my subscriptions renew themselves, I have to also be notified of random games going on sale, too.
This should be better with /e/OS or lineageOS, but you have to jump through several hoops (and often lose your warranty) when you install them instead of your default Android OS.
Unfortunately most devices block them completely, but the Pixel phones are supported (as far as I know).
i run rooted LinageOS 21 with the Zygisk Assistant and Play Integrity Fix modules. No app can detect i use a custom rooted rom. Google wallet and my banking apps work just fine. And i can do whatever the fuck I want with my phone since it's rooted. For example with AdAway all ads are gone. I love it.
