Can't click Rematch

I'm using Edge Chromium Version 89.0.774.54 on Windows 10 20H2 build 19042.867. I've recently come across this when my opponent issues a rematch, the rematch button animates and tells me my opponent wants a rematch, but I can't click the button and the mouse over shows red circle with cross on it. Seems like a bug to me!

If your opponent wanted a rematch, but when you didn't accept it your opponent left, then you will not be able to click the rematch button anymore and you can only click the decline rematch button

yaaaa

No, in my case, when my opponent leaves, I can click the Rematch. That is, when I click that, automatically, my opponent gets challenged by me with the same time control
