Unbelievable that in every app, how can make offline Synchronisation other bugs are exist.
I searched a solution for my Ipad, Iphone in Combination with Synology NAS.
The Synology solution dont exist anymore ("DS Cloud") and also the app was not really supported.
Now Resilo was a solution, but i have to always on the display, otherwise the app will not update.
Is it so unusally that i want my NAS Datas offline synchron? Incredible
