I download the apk file from Whatsapp website to install in GrapheneOS, and I've noticed that notifications for messages are very delayed from 15 minutes to no notifications at all until I turn on phone screen and then all of the messages come through. Is there other Whatsapp users with similar issues with functionality?
Signal functions good but there have been times of small delays with messages coming through to get a notification.
I know Services is available in a sandbox, I didn't think of that, presumably because I view it either with disdan or treat is not an option. There's also MicroG which I've never been interested in trying.
