On my Macbook Pro, I use Path Finder, a Finder replacement with dual listers (similar to Directory Opus on Mac). The latest update has the following note:
"• WARNING: removed quick file uploader to Google Drive! This is done due to Google's ridiculous "Cloud Application Security Assessment (CASA)" security review procedure, which caused many small independent macOS developer companies to abandon and remove Google Drive related functionality, even for products which sole purpose is cloud/remote files management. NOTE: with Google Drive macOS desktop application installed and running, users will still be able to access their remote files on Google Drive like local files in Path Finder (and Apple's Finder), just like they have been doing it before. Only the quick uploader to Google Drive was removed. We apologize about the inconvenience, but we were practically forced to remove this functionality, now that Path Finder's annual Google verification period has expired."
This isn't the only app I've seen that is removing Google Drive access. Panels, a comic book reader for iPadOS, has removed access to Google Drive.
I have a 2 TB GDrive account that I've enjoyed since the days of Amazon Drive. I'm sure I'm not the only one. Is it time to see what other cloud service will meet my needs?
(Not asking for tech support, but I'm curious what others have done.)
