Hi, thank you for replying to my post.
Unfortunately it is continuing. I just played around a bit, first, no files were loaded for several minutes, no matter what I did, Wifi, 4G, Force quitting App and reopening.
Then, suddenly it worked, after I had been occupied with other stuff. This is already something, but I hope you can understand, that it is not easy to work like this, its a bit of a lottery. Would be great, if the synchronization process could be improved somehow.
For the logging out issue I found a workaround, whenever it asks me to log in again, I force quit the app and restart it, that helps for the moment.
