Anyone still having problems with message + not syncing? I have android 8.1 on phone &.7.0 on tablet and sometimes it will show a message sometimes not. I tried reloading the app all over and it still does it. It also says no phone service available, when setting up the app on the tablet 817V and scanning the code with tablet during setup, even though I have HD messaging, great LTE service and video messaging on phone!
