After a recent update can no longer click on the topmost subscription groups. There are now for some reason three white distracting circles on top (background), which not only distract, but also makes clicking on the topmost subscription groups brings the sorting menu instead of opening them... Not sure the circles are done by you or Youtube, anyway only way to fix is to hide the circles using ublock picker.
UPD: The new version 11.1.13 is available on Firefox. -- Yes, it happened to me too. It is a youtube update https://theverge.com/2022/4/12/23022541/youtube-sidebar-outage-settings-account-switch-sign-in I've prepared a quick fix on the extension side. It'll be available after approving the new version soon. I'll notify you.
