Me Too button isn't working

[JanS2000]

Morning, I've published a couple of problems to our self-service portal as known issues. They look okay to me but when me or any colleagues click the Me Too button on either one, nothing happens - we just get a scrolling wheel that goes round forever and doesn't do anything. I've been reading the guidance on the wiki to see if any special permissions are required, but it doesn't look like there are. I've also checked the advanced and core settings but nothing stands out. Has anyone else experienced this or is it likely I've set something up wrong?

Morning, could it be that something on our side is blocking it?
