On my phone the new version hasn’t solved the problem.
My first test was just updating the app from 1.36 to 1.40.1 and disabling/enabling the push function as descript in the upper topic. With around 50 folder it takes some time to do that, that is not very handy. After disabling I have restarted the app and the phone as well.
The second test was deinstalling and reinstalling the app but that also does not fix it. Here I must activated for each folder that is should be synchronized and activate push. With 50 folder it is quit boring, no idea why that cannot be set automatically for all folders.
Another problem with the versions high 1.36 is that the update of the folder takes a long time. For every folder it takes around 3 seconds.
I have to go back to 1.36 to use the app.
