Samsung Q9 and Q90 Tv's not recognised as wireless monitor on windows 11 laptop after TV firmware updates

After recent firmware update to my Q9 and Q90 64" TV's , both have become invisible to my Windows 11 laptop as a wireless display.

The TV's are visible and usable to my iphone, Fire Tablet  and my laptop can see all other TV's in the house including a Samsung UE43AU8000KXXU as well as Sony and Phillips TV's.

Samsung told me that there is no problem with their firmware or it would have affected my iphone too.... I disagree with them. Has anyone else got an issue?  The laptop was working fine with the TV before the latest firmware update..

So I have got around the problem by installing an Amazon Firestick which is picked up by my Windows 11 laptop and I can stream to it perfectly? Come on Samsung a Firestick is doing what my “Flagship” TV can’t? Will you please investigate what has gone wrong with your software update?
