After updating to Tahoe 26.0 Roku no longer appears in Displays
This was working with few issues before the update. (There are significant bugs in using AirPlay which is not related to this issue.) After updating to Tahoe 26.0, when I tried to mirror to my Roku Streaming Stick, which is attached to my TV, I no longer have the upper right pulldown menu where I can select the Roku device. The Roku device seems to be working fine, though I had to power cycle it to get the home page to appear. I'll search for this issue elsewhere, but I don't see why an OS upgrade would break Airplay.
