Paste function no longer works in Outlook email (web version)

Hi,

I've been using copy and paste frequently in my work Outlook account for almost two years without any issues.

The other day I found I could no longer paste text into the email body. It doesn't matter where it's from, and copy works fine, just not paste.

What happened just prior to this was a window popped up saying something about allow or block pasting from clipboard, but I didn't read it properly and clicked block, and suddenly it wouldn't let me paste anything (unsurprisingly... just I'd never seen that pop-up before so it caught me off guard and I didn't know if it was genuine)

Anyway, I closed the app and reopened it and tried again. This time the pop-up appeared again and I clicked 'allow' and thought it was all fine.

It still wouldn't allow me to paste, so I closed the app again, reopened it, and it was working, which it continued to do all day.

The next day (yesterday) I opened it as usual, no pop-up, but it wouldn't let me paste. Now if I click on paste, the options box just hangs there and doesn't disappear, and it still won't let me paste.

The only thing I can think is there was an update the other day and I wonder if there's a bug in the new version.

Does anyone know how I can revert to a prior version perhaps? I really need this function for work, it's disabling without it.

Many thanks.

ETA: I've just tried using ctrl+shift+v and that allows me to paste. So this is something to do with Outlook itself I think. But I have a workaround for the time being, if that helps anyone with the same issue.
