I’ve just created my account and for my first project, I can go ahead because rectangles disseappered as soon as I drawn them. I don’t know why. Someone to help me fixe this issue
Hi there, welcome to the community! This looks odd, I can’t reproduce on my end 
I’d like to get some more context to help troubleshoot.
To start off, can you let me know if this happens in the desktop app, web browser, or both? Can you also let me know if this happens in any Figma file or only certain files?
Also please share a quick video recording so we can better visualise your issue and try to replicate it. Thank you!
