I have the problem or rather the suggestion that they introduce it to upload only one folder to iCloud. I use Goodnotes for school and have the problem that I have to upload all the documents from the last few years to iCloud so that I can see them on several devices. Actually, I only want to see the current folder on other devices. But now my iCloud storage is full and I can't synchronize anything. My suggestion would be that they introduce the ability to synchronize folders in the iCloud so that the iCloud storage is not exhausted.
Many thanks in advance
