TV-OS-26 broke Airplay on my Gen 4 AppleTV.

After years of happy watching on my telly my Apple TV Updated last night. Now I can't Airplay anymore. I can still mirror my screen, watch library stuff, but no Airplay anymore. The function I bought that thing for doesn't work anymore. Great. Internal Server Error or some such is what Airflow gives me.

Everything on the same router through LAN connections, nothing changed except for the TV OS update. Now what? I take it there's no way to 'downgrade' to what I had? Which worked great.

Most frustrating in my view is that there's no way for me to let Apple Tech know about the problem. What a mess. Besides all that I think '26' looks way beyond ugly.

UPDATE! Elmedia Player, which I always use but somehow didn't for Airplay, has released an app update. I just checked it and lo and behold, Airplay to my Apple TV 4k is working again. I'm watching as we speak. No news yet from AirParrot or Airflow, but this proves the problem is indeed with Apple TV OS 26 and that it is still possible to get it working on for instance Monterey. No excuse for developers, nor for Apple either to get it fixed in the first place.

I would suggest turning off automatic updates during school hours, tell students to update iOS at home before coming to school. Do school updates overnight or during weekends. I just woke up to an iOS 26.01 update, I had forgotten to tell it to not auto update yet.

it just sounds like the automatic update hit a whole bunch of devices at once and that’s probably what all of the activity at your school was.

The thing is the problem went on even after we turned all iOS update traffic to zero so it didn't have a lot to do with it. But yeah, we now have our temporary rules in place so no iOS device updates within the "working hours" so the problem itself made us optimize the whole network and load by a lot. Both teachers and students now have to update at home and school devices only update in holidays or on weekends when we want them

to. 👍🏽

Well good for you.

I did upgrade Airflow and still not working. I've attached a screenshot of the problem. If someone know what to do, I am listening.

FYI : I did not change ANYTHING to my configuration since the issue happens.

I am not streaming at all and I never mentioned streaming. I'm playing films on my iMac through a player or an application to my Apple TV on an all wired network. Well, that was what I was doing.
