Have you tried to share a QS download link via Facebook/Messenger?

websafe

The link is unusabe, because FB adds "?fbclid=..." and it destroys everything.

When one shares a link link like this https://get.teamviewer.com/xxxxxxxx
via FB / Messenger the receiving part will be redirected to 
https://get.teamviewer.com/XXXXXX
which will not start the download as expected but ask to join a session...

Please fix this.

Using link shorteners does not help either.
