AirPlay no longer works on Samsung TV

"AirPlay no longer works on Samsung TV: I used to be able to cast from my iPhone to my Samsung tv using AirPlay. It no longer works. Yes, both devices are on the same wifi network, I reset both devices, and even reset my network on my iPhone. Nothing works. Any ideas?"

Update your Devices' Firmware:

I. Updating the Smart TV:

See if there is a way to update the firmware on the Smart TV.

II. Updating an iPhone:

Use my User Tips:

• Computer:  Update your iPhone Using a Computer - User Tip
• Cellular: Use an iPhone 12 or later, that is using 5G, in order to update over Cellular - User Tip

B. Backup Prior to Updating:

IMPORTANT: If you have an option to update, however, then be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the update
