After reading several threads about connecting LibreOffice to a Google Drive account it appears that there is no solution that resolves the problem of needing a 6 digit pin from Google that never arrives.
If there is a working step by step, illustrated solution, I’d sure like to know what it is. If not, I suggest a LibreOffice with developer access simply remove this as an option since it doesn’t work.
Google knows my phone number. There’s no unresolved security issue relative to LibreOffice being granted assess to my drive account.
