Since doing some app updates notifications for MMS are not working unless mobile data is turned on. This was NOT a system update, just apps. It is non functioning on the default app and chomp ( the app I use regularly). I'm not talking about receiving the MMS, just the notification that there is a message. It worked yesterday. All the notification settings are correct on both apps. I have disabled the default app, cleared the cache on both apps, cleared the cache partition,and a soft reset. Nothing helps. It is running android 8 so doesn't have the option to toggle on the "receive MMS with mobile data off" option. Any ideas anyone?
