Airplay no longer working
I've been using airplay on my iphone 13 successfully for quite some time, mirroring to several Roku sticks and Roku smart tvs. Suddenly, none of the Roku devices are showing up on my iphone. I've restarted all devices, verified that all are on the same network, verified that I'm running the latest releases on roku and iphone, etc. I've also contacted Rokus support who could not help me.
iPhone 13, iOS 16
