So, after digging a bit I found this Reddit thread:
from r/ZeroMotorcycles
Looks like this is related to Zero's cloud service not working after they released an update to their app.
Not entirely sure, but the problem might be that the new app was launched in some markets but not all, while the cloud service is global and wont work with the old app. So, I might have the old app trying to talk to a new Cloud API, and thus failing?
Perhaps a workaround is to VPN to USA, and change the Play store location, then perhaps the new compatible app can be installed - or it would just have you tumble down another rabbit hole of issues.
Apparently Zero is aware of the problem and are working on it. The problem was reported ten days ago though, and it is still here. Knowing they initially announced the Cypher Store would be available "soon" for over a year, I would not hold my breath.
