It's a bit tricky to downgrade the go app on iOS you need to go threw a 3rd party unless you have backed up your iPhone hence the reason I have to use a Spaire old android phone I have , but I would seriously put money on it your problem is the go app,, I accidentally had auto update apps turned on my iPhone hence why I'm in same situation on iOS , best of it I'm aware of the problem of the go app and auto update should always be turned of on phone,,, I no I no I forgot,,,,, I've helped quite a few lads on the phantom groups to overcome this signal/range issue problem
