Good but has Google issues
I love Notes Plus and now the newer Notes Plus X. The app is easy to use. My issue with it is using it with Google Drive storage. I have done all sorts of tests, workarounds and reinstallations, but Notes Plus X fails to create documents in Google Drive and crashes the iPadOS Files app. Saving PDFs in Drive is fine, but making and saving notes plus document files just hangs (it shows as not uploaded and greyed out). I have had to resort to saving documents in iCloud Drive which works. I have emailed the developer about this. At the moment, the app is unusable within Google Drive to save notebooks.
