No longer receive notifications of any kind on the IOS SatelliteGuys app. The last notification received was on April 12. Have logged out/in and reinstalled the app. Yes, all notifications are turned on in the settings.
When I googled Tapatalk Notifications Not Working, i found a bunch of stuff about it. Over the years that seems to be a very unreliable feature. It seems that things like reinstalling the app never made a difference. It is always their fault, because with whatever's they're playing with again, they manage to screw this up.
I have the AC Forums app installed on my LG G6 and it is based in Tapatalk like the Satelliteguys Reader and I get push notifications there. So it must be something with the Satelliteguys server or something.
