Thanks for reaching out using Apple Support Communities!
We understand that AirPlay is no longer in perfect sync after the last update you installed.
We'll want to make sure that all devices connected are using the latest OS versions.
Here are the steps to Update your iPhone, iPad, or iPod touch - Apple Support

After all updates are installed, try again to Use AirPlay to stream video or mirror the screen of your iPhone, iPad, or iPod touch - Apple Support
We hope these steps can fully resolve the sync issue between your devices.
