I have bought a new pixel 9 and installed latest GOS on it, after a week of use or so I can reliably say that I don't get calls on whatsap also not on signal, unless i open the app.
I have sabdboxed google play services installed, and installed the apps form the PlayStore,
i have set battery unrestricted and don't manage this apps and alowed background data,
then rebooted the device for good measure but no change still the same problem.
This is really not good, is there a known issue in android 15 based GOS? I really need to be reachable with messengers.
Please advise.
