Evernote 10.1 can't synchronize with the server.

[DeveloperKarl 0]

Device:
iPhone XR

iOS version:
iOS 14.2 (18B92)

Evernote version:
10.1 (1107121)

After I upgraded my Evernote to 10.1, it can't synchronize with the server anymore.

For example, I have deleted a notebook elsewhere, but this notebook remains on my iOS Evernote and I can't delete it or remove it from its original stack.
The attached gif shows the bug I mentioned above.

I've already tried to reinstall Evernote or click 'sync now' button manually, but those don't work.
