yep always the exact same one!
in my settings for “On start-up” I have it set to “Open a specific page or set of pages”, with a link to my calendar (made sure url wasn’t wrong).
but, if I change “On start-up” to any of the other options, or put in a different url nothing changes, it still opens the one same page.
tested this with all my extensions disabled and no changes, same issue still occurs.
doesnt happen in a new profile
