Well, I'm glad to see this thread... it gives me some hope the issue I ran into this morning might get fixed soon...
It was a nice Sunday here in LA and I decided just to update everything, including the new Studio Display I've had for 10 days. Mine was on firmware 15.3 and I saw a 15.4 was available but googling around told me first I had to update my OS from 12.1 to 12.3.1. I did that update with no problems.
With 12.3.1 installed I did indeed finally see an update to firmware 15.4 for the Display. Tried that but after about 20 minutes the whole screen was black with an error message at the center saying the update failed and to go to support.apple.com/display/restore for info. (There was no mention of waiting an hour and retrying as it seems some people got in a warning message a month ago.) The info on that page was a bit confusing. They wanted me to attach another monitor to my Mac Mini to complete the installation, but there was no mention of what to do about the Studio Display itself. (Is the firmware for the Display in the Mac Mini?) Anyway, I don't have an extra display so the advice said in that case call Apple. I called and they couldn't figure anything out over the phone and told me to take it to an Apple Store. Luckily there is an Apple Store about half a mile from me so I go on the wait list for a service appointment and after 2 hours they were able to take a look at it.
The very friendly and apologetic folks at the Apple Store said this was the first time they'd seen the issue and quoted me 3-5 days to fix it, but hopefully less. So now it's sitting with the Apple Store.
Taught me a lesson not to update the thing if it's working fine, which it was...
