Clipboard Doesn't Work

For meetings with moderator (me) and one other participant, clipboard has stopped working. I was always able to paste meeting name from clipboard to email message to participant. Now paste function doesn’t work. What has changed? I use MacBook Pro OS 13.6, Firefox (current version), and ExpressVPN. The other participant uses Samsung Galaxy Note 9 and Android. We have not changed anything in our hardware or software. We haven’t had a problem until recently. (I can start the meeting by typing the meeting name into my email message.)
