I have the same issue, being prompted for the program to use to open Word, Excel, etc., files.
My right-click context menu for New contains 5 entries. No New Folder, Excel spreadsheet, Word document, etc.
And in File Manager, the New Folder button is not working. It seems the only way to add a new folder at this point is to use my laptop, and that only works for OneDrive files.
Not too confident these will get restored with any Evernote update...
