I uninstalled all 3 Play service components to test something and then reinstalled them again. Unfortunately, this resulted in some apps (like Whatsapp and Signal) to stop pushing their notifications. It's like they didn't switch back to receiving their push messages through Google Play Services. The only way I found to fix it for these apps was to completely delete their data and set them up all over again.
Is there any way to make sure that the rest of my apps also recognizes and uses the Play Services again? I just want to make sure I'm not missing any notifications or unnecessarily draining battery through a custom push implementation somewhere.
