In testing, I can achieve synchronization across my 2 mobile apps, creating accounts, logging in and storing data that can be changed and reflected across both native apps.
But I have one account, the main account with which I’ve done the most testing, where synchronization has broken. After entering 4 records, synchronization has stopped. Logging in and out doesn’t restore synchronization. However, the records I add and edit on the device are maintained. So I can login and logout without losing the data on the device, it just won’t get synchronized to Realm and reflected across apps. I can even create another account on the same device and create records that are synched accurately, then logout and log back into the broken account and see all of the correct records, just still not synched.
So something happened at some random point that broke synchronization on that specific account. I don’t see any errors in the logs that I can link to this. The only thing I can think to work on at the moment is trying to verify if the realm on the device is the same as the one that is partially synched and visible on the web admin.

Hi Ryan,
Are you getting any errors in your client app?
Please also check your Realm Logs and filter by Errors and Sync categories, you can also filter using the user ID you’re logging in with. Are there any errors which occurred around the time your reproduced this issue?
Have you tried terminating sync recently? The client will need to be reset after a termination happens. If this is the case, please try uninstalling the app on the client and re-installing. See article below regarding setting up client reset handling automatically.

I’ve gone through the Realm logs and there are no error logs.
I’m now receiving a bad changeset error.
