My team is on the Dropbox Business Standard account, and I am one of the admins. The dropbox app (v157.4.4801) on osx (Monterey 12.2.1 (21D62)) just gave the following notice:

Neither me or another admin changed anything in our account.
I went into the 'activity log' and didn't see the notice there.
When looking at the Settings > Sync I don't see anything that indicated that the settings has been disabled:

I indeed notice that new files are not 'online only'.
Am I missing a setting here? I want (and need) new files to be online-only.
Update after ~12 hours: The notice is gone, and files are syncing online-only as they are supposed to. Was it a temporary bug?
