In addition to what the title says, I found that there was a red-herring right arrow that does nothing on the Sync detail page and render.com spontaneously logged me out for no clear reason.
Hi @samuela ,
Thanks for the feedback 
I’ve put this into our issue tracker so we can take a look and improve it.
Looking at your account, it seems that you were able to get a successful sync. Is there anything I can do to help, or are you set for now?
