Keepass2 won't sync

I am trying to get Cryptomator to work with Keepass2 on Android 6.02. I am getting a “Permission Denial” error similar to the one in this issue

I don’t really understand all this but it seems there may be a possible fix in 1.x? Can anyone confirm this?

As described in this post File permission for third party apps Keepass2 has no WRITE permission to the keepass file opened from the Cryptomator app.

We are planing in a future release to enable third party apps with WRITE permission and write back changes to the cloud.

In the mean time try out the following workaround Export keepass file from Cryptomator.
