I had two Cat 1-4 certs expiring 12/31. I had asked on twitter to get them extended and they were non-committal as late as a couple of weeks ago. On Sunday, I booked two nights at a Cat 4 hotel, then I sent a message on twitter asking to cancel them because of Covid. The rep cancelled my reservation, and added two Cat 1-4 certs to my account with an expiration date of 6/19/2022. Looks like they may be extending the certs for ~6 months if you ask.
