Iphone not Synchronising in Private Home Cloud


I’ve set up a private cloud on my home network using Seadrive 6.0.7. It’s only accessable within my home network.
I have an android and my girlfriend has an Iphone.
The sync on the android is working great, but the Iphone only syncs if she has the application open.
It will never sync in the background nor if the location changes.

I have followed some of the workarounds/fixes suggested on this forum:
-Enabled background sync on iphone
-Enabled Location tracking/services on iphone
-Reinstalled app
-Turned Auto Upload off and on

The Iphone is using IOS 10.3.3 and version 2.6.3 of the seafile client.

I do not know if it’s a different scenario with Home Private Cloud vs Cloud, but I wanted to ask anyway.

Is a fix for this under way and does anybody have any other suggestion on how to get around this?
Appreciate all the help and great work so far on the application.
