It's clearly the same issue: the security credentials are missing from keychain so the app cannot authenticate. We are still puzzled to what could be the root cause of this issue. We have added checks to make sure we don't mess with it.
Have you at any point deleted the SENSE app from your phone and re-installed it? That is the only scenario which we are aware of that would delete the keys from the keychain. iCloud backup doesn't backup or restore the values in the keychain and we end up in this scenario.
