Need to "download proprietary daemon" every time Xubuntu restart.

[eurico]

I have installed Dropbox successfully on Xubuntu 19.10 using the 64-bit .deb installer from from https://www.dropbox.com.

But there is a problem, because every time Xubuntu restarts appears a pop-up window from Drobox saying "Dropbox is the easiest way to share ... to blablabla... you must download proprietary daemon ... blablabla". This happens every time the system starts. And then I click ok, the daemon gets intalled again and Dropbox works fine. Sometimes, I click cancel and Dropbox works fine too, but in some opportunities by clicking cancel Dropbox does not works. All the Dropbox requirements are ok, my machine configs are ok too.   

So my question is, what is the problem? And how can I solve this?

I already have said everything I can. I believe that everything is clear. If there is something else I can add, You or somebody from backteam can ask me, I would be happy to help further. I want to note that statements, like a discrepancy related to feature description and actual feature are new feature request, is more than disappointing!
