I think I was able to reschedule myself to a different flight on Wednesday. Their website seemed to have crashed at the end of the process. The website shows my new flight for my original reference number but I did not received a confirmation email.

Other than that issue, I actually don't have any complaints about Ryanair. They let me change my destination from Edinburgh to Glasgow. I don't think they will pay for an extra nights hotel room since the cancellation is due to a strike.
