Mobile Auto Upload not working after NC15 -> NC16 upgrade

After upgrading from NC15 to NC16, the autosync functionality of the Android nextcloud app is no longer working. I can manually upload files from the app, but no autosync.

I do not have any errors in any of the logs, so I’m at a bit of a loss. Any ideas would be appreciated.

Nextcloud version:
Operating system and version: Debian 9.8
Apache or nginx version _(eg, Apache: 2.4.25
PHP version: 7.2

Thank you
