Jack,
Thanks for the answer. My experience so far is that it takes MUCH longer to open files, sometimes 15 seconds to open an excel file compared to a few second before. When I open an RStudio project it can take 30 seconds before the file pane opens - for files that are "Always on disk". It appears the commit messages reference the hidden location under library and not the "OneDrive" location. so it is NOT the same experience as before, even after several days of clean up. I did not sign up to be an alpha tester.
I am getting a constant message from Finder that, despite being signed in to OneDrive and it synching and synching, that it can't open the Helper function and therefore can't complete a file operation.
The OneDrive icon in the top of the screen is useless as it tells me it is now synching over 1800 files yet only shows files it synched hours ago. I have no idea what is actually doing to my machine. Needless to say the constant synching slows down my machine so maybe that is why a theoretical "same experience" is meaningless for an actual user. I did not sign up to be an alpha tester.
I lost links to several shared drives with others and had to recreate them on OneDrive. Not all went away but several did.
I am still cleaning up the mess in GitHub as changing every file location meant every file I had in a repo had to have a new commit history. Several repos got corrupted as the OneDrive update occurred without any prompting while I was teaching class and had open files that were both in OneDrive and GitHub. It created copies of files with new names, some of which were not open and without warning. It is taking hours to both clean up the corrupted repos where GitHub and Git can't agree on what files are where and how to deal with it. It kept timing out over and over despite increasing cache, adjusting compression, and trying every hack I could find on line. I finally had to delete my local .git, do a git pull and am in the hours long process of going folder by folder (since the repo is too large to do all at once) and recommit all the files again. I did not sign up to be an alpha tester.
Bottom line, I have used OneDrive for years with minimal issues in both personal and enterprise settings and this experience is NOTHING like what I had before. If you think it is then I welcome you join my world for a different perspective.
