I have been using Figma for several months now. I am using the desktop app on Mac. When you drag an object around it used to show red alignment lines which automatically appeared/disappeared to indicate when your object was in alignment with the centres or edges of other objects.
This stopped working a few weeks ago. I am not sure in which version it stopped, but I do update regularly. I am currently using version 102.9 on macOS Big Sur 11.4.
At first I thought I was going mad and it was a setting or flag I had changed, but I have just double checked the browser version in Firefox 91.02 and it works fine.
Is this a bug?
Cheers Simon.
