Here's a page describing forms and situations it does not handle [1].
One thing that might annoy some people is that to login to the Cash App Taxes website you must use their mobile app. The website shows a QR code which you scan from the mobile app.
It uses the approach of asking you various questions in order to figure out what forms it thinks you need to file, which is an approach that some people do not like.
If there is a form you know you have to do that it missed or you have a 1099-something that it has not asked you to enter it took me a little while to figure out how to deal with that. What you do is type the name of the form into the help search box. One of the results will be a link to take you directly to the page that deals with that form.
