I am experiencing the same issue as many users.
No matter how many times I ask my files to stored offline, some of them never sync, so I need to manually download them from my Dropbox online account and place them in my local folder again. This makes my workflow slow, and is absolutely against why I have Dropbox in the first place.
Dropbox version: 223.4.4909
MacBook pro (M3), Sonoma version 14.7.4
