Dropbox won't be fully functional when macOS 12.3 arrives
Dropbox is warning users about known issues accessing online-only files from third-party applications after updating to macOS 12.3.

In an email to customers on Tuesday, Dropbox is warning that online-only files won't be able to be read by third-party apps by double-clicking on them. The same email also addresses how to work around the problem.
Those wishing to access their files via a third-party program will need to employ a workaround that involves downloading the files to their Mac with the same double-click to open in Finder, but there will be a pause as the file downloads. Users must move all online-only files to local storage if they need to access them in third-party programs until Dropbox fixes the issue.
In short, files labeled with a small cloud icon will need to be downloaded before accessing the contents of the file, instead of opening the file directly on the file share without a full download.
Alternatively, users can make an online-only file available to third-party applications.
Dropbox clarifies that it will begin rolling out a beta version with a fix sometime in March.
Apple's macOS 12.2 is imminent, and Dropbox will work fine when it arrives. Betas of macOS 12.3 haven't been released to the public yet, but it's clear that Dropbox has inside information on the contents and limitations of it.
Should you want to access the beta release when it becomes available, you can opt into Dropbox betas by following the steps on Dropbox's website.

- Open the Dropbox folder in Finder
- Right click the file you want to make available to third-party programs
- Click Make available offline, which will download the file to the Dropbox folder

I will no longer use the Dropbox client on my Mac because it randomly deleted many of my files due to sync bugs - luckily I noticed this and was able to resurrect in time.
If iCloud + started focussing on their data storage service offering to meet and exceed DropBox - I’d drop Dropbox in a heartbeat.
a. They try to hijack your photos (and likely monetize them)
b. Their free tier is ludicrously stingy and their paid tiers have problems like the one described above
c. I don’t trust them with my data (especially compared with iCloud)
d. They have a war criminal on their BOD
So far you can't do that, iCloud Drive only works to share w/ another iCloud user, and it adds it as a virtual-folder in their iCloud. It would be 100% if iCloud let anonymous recipients view the contents via a URL in-browser.
I don't know of a solution as of yet. Any advice (besides leaving Dropbox for another service)?
