That did not change anything. I still can’t reproduce locally.
Not sure if it is worth nothing, but this text changes for time to time when viewing the error logs.
Also, it is a possible a partial sync would be causing these errors to surface? For example, a user over a non-wifi connection cannot complete the full sync and a Sync connection was not fully established in time error is thrown. The app is now partially synced. Would that possibly cause the strange field encoding and schema change error?
