Changing edit and sync settings in a certain order of a parent layer causes its associated view layer to return the error message, “Save wasn't successful. Try again later" when saving editing settings of the view layer.

Workaround

1. Disable all editing settings such as, Enable editing, Keep track of created and updated features, Keep track of who created and last updated features, and Enable sync of the parent layer and its associated view layer.
2. Re-enable all settings in the parent layer, and re-enable all settings in its view layer. Sync can be enabled successfully.
