Nextcloud Full Sync Android Devices

I use Nextcloud 21.
My clients are notebooks and Android devices.
I synchronize the notebooks bi-directionally with the help of the desktop application. That means, all data that are in NC are also locally on the notebook. Changes are automatically synchronized.
The Android client has not been synchronized in this way with the aid of the Android app. In order to have all data available locally on the Android device and to automatically synchronize every change, I previously had to use the FolderSync app.
Can you get this guaranteed without FolderSync?

Repost of Nextcloud Full Sync Android Client?

I was about to suggest rather posting on the Nextcloud forum as there Nextcloud users are probably more active, but I have seen you’ve already done that.

Thanks for your hint.
