Hi,
I’ve (finally - by chance) reproduced the connection problem I’ve seen occasionally in the analytics - it wasn’t causing app crashes for you, just a seeming inability to connect. It seems the root cause is a bug on the device side code. And by chance, girts might be already investigating this problem.
