Connect IQ apps data stops

So I'm using the TyreWiz Data Field and it will show my tire pressure to begin but after a short while it will kind of 'die' and just show the connect IQ app icon.

My so called fix, I've found is just holding the power button and doing a reboot cycle. Obviously this is pretty tiring and not ideal for such a costly unit. 

Is there an actual fix, or is this just how it is?
