iPad will only mirror on Apple TV for a split second

Good day supasooner,

If you are having an issue with being unable to use AirPlay mirroring from your iPad because it stops immediately after starting, I would suggest that you troubleshoot using the steps in this article -

Get help using AirPlay and AirPlay Mirroring on your iPhone, iPad, or iPod touch - Apple Support

Specifically the section titled If your playback is interrupted, or you have network lag.

You might notice these issues if you have a weak Wi-Fi signal or interference from a different device, like a microwave or baby monitor. Try these steps:

1. Make sure that you're using the recommended settings for your Wi-Fi router.
2. Move or turn off other devices that might cause interference.
3. Try connecting your Apple TV directly to the router using an Ethernet cable instead of Wi-Fi.

Thanks for using Apple Support Communities.

Safe computing,

Brett L
