Hello, I have been using GrapheneOS happily for a year now on my P8P. However, there is one problem that has pervaded me intermittently ever since i started using it.
For some reason, push notifications from certain apps will not appear, most notably chat apps and even the GOS stock "Messaging" app. This happens at least once a day and has been consistent for the entire year I've been using GOS; it is very annoying since it leads to me missing messages from family and friends until much later when i open the app to check, only to find they had messaged me hours ago. It happens rarely, but this has even happened to me with Phone calls, where for some reason the phone did not ring and i find a missed call later on in the day.
I am using GOS release 2025021100 on a Pixel 8 Pro. I have multiple user profiles, but 99% of the time i am on the Owner profile. I have ensured that Google Play services has all the necessary permissions (ex. unrestricted battery) pertaining to push notification delivery. I have verified that this behavior occurs even when Do Not Disturb is enabled. I am using Mullvad VPN constantly and also using a NextDNS privateDNS endpoint. Additionally, I am using a Pixel Watch 2 that is connected to the phone via Bluetooth.
Has anyone else encountered this issue?
