I cannot help with this issue but on my side I see a similair issue. I started to use brand new Android 10 device and installed Evernote. The installation happened seemless but I cannot save a new Note on this device. Syncing notes and editing notes is all fine but not able to save a new note. When i try to save a new note the green hook in the left top site does not get green to indicate there is a change and it's not klickable but greyed out.
i tried to add all available app permissions on android system level but no effect on this.
Any ideas?
I have another Android Smartphon in use which does not show same effect.
