Hi @guddl,
nope, this is a known issue, see https://github.com/nextcloud/android/issues/110 and Direct upload photos doesn’t work
This is due to the fact that Google complete changed the way services and background processing works from Android N onward. I myself am using the latest Android N beta. The necessary changes haven’t been investigated in detail yet and I wouldn’t expect a “fix” before the End of September (or later).
At the moment the App is mainly maintained by @tobiasKaminsky and me, so it is also a matter of resources.
Best regards,
Andy
