OneDrive keeps moving to bottom of Finder Favorites
I'm on a MacBook Pro early 2015 running OS 10.14.6. I have a subscription for MS Office and had previously installed it through the App store. The App store notified me that updates were available; however, they wouldn't download (the wheel kept spinning forever). Microsoft told me that MS Office through the App store has limited features, so I downloaded MS Office from their website and installed it that way.
I put the OneDrive icon at the top of my Favorites in Finder.
Now, every time I restart, the OneDrive icon ends up at the bottom of my Finder Favorites.
I saw an online article that said that installing OneDrive through the App store fixes the problem:
However, when I try to install OneDrive through the App store, I can't download it – the wheel just spins forever.
Is it because I'm running OS 10.14.6? I don't want to update to Catalina because the versions of some of my work software (video editing) isn't supported in Catalina.
