Impossible to use multiple Dropboxes
I configured multiple Dropboxes in one NextCloud Instance. This resulted in having contents of them mixed up but not accessible in NextCloud WebUI. Also at least Linux Desktop Client is not able to correctly sync them.
This occurs no matter if those are configured by admin and assigned to user or by specific user directly.
I'm experiencing this as well. Being able to add multiple accounts would be a great addition.
It is possible, just make unique names like here:
you will get something like this:

That's exactly what i've done, but content is the same as the first dropbox and exactly the same size.
