In order to reduce the load on the server, synchronization is a mechanism to temporarily cancel up to 100 cases at a time. The fact that this display appears means that data was accumulated on the Android device side.
I think you can see the progress in the notification bar. Repeat the sync operation until it reaches 100%. If there are 200 fields or work histories, it is necessary to perform the synchronization work twice.

Even if it takes time, please wait until it reaches 100% anyway.
