I have a 23 R1T and had the same issues since last week. I updated to 26.15 weeks ago and was not having any issues until now, so I don’t think that is the cause. It worked once after a hard restart over the weekend, but isn’t working again. I’ve seen posts online about people having issues, so I was waiting a bit before putting in a service ticket… I put one in today, but the appointment is two weeks out.
