Hi @aviete.pi, @thorneyroad, @drag_knee,
That message is a result of a server change we did earlier this month which causes the Android app to start erroring out in certain conditions. We are aware of the issue and currently testing a build which resolves this. As you've found, re-installing the app (or taking the less drastic step of force-stopping the app and 'Clear Data' in your Android application manager) will grant at least temporary relief from the issue.
We know it can re-occur by closing the app, so we're recommending that you just background it when not in use until we have a fix out the door. For some users, they've reported that the error still occasionally recurs even when taking care not to close the app. So if it does, repeat the above steps to get it working again. If it fits into your workflow, you may want to consider using the Cayenne web dashboard until the Android app gets this update.
Certainly I'm pulling for a release by the end of the week so we can put this behind us. I've added your names to a list to notify when the bug is fixed and I'll be sure to post in this thread as well.
Thanks for your patience while we resolve this and apologies for the inconvenience.
