I'm in the same boat as everyone else with this. Same errors etc
Tried to update which has downgraded the remote app, MTO4 downloaded but wouldn't run, neither would MTO3 which, when it gave the error message reinstalled software which suddenly meant MTO3 stated working again.
I wiped the box and got the same android lying flat with an error message.
The weather doesn't show, the remote app is showing old versions, the new hotfix doesn't show up either.
I think one of the beta versions has done something screwy. I still have MTO3 working now so just going to leave it for now because there's something definitely odd going on.
