iPad no longer mirroring full screen

As of today, my iPad no longer mirrors to my Apple TV full screen. I’ve checked to make sure both software systems are up-to-date and restarted both machines.

Yesterday I was mirroring content, streaming from my iPad to my TV and it was running full screen. When I attempt it today and switch to full screen the iPad is mirrored at aspect ratio — tiny in the middle of the TV screen. I’ve made zero changes to any settings (was at work all day today).

Again, my iPad has been mirroring through my Apple TV full screen since I got it almost exactly a year ago without issue.

I just started mirroring from my MacBook and it displays full screen no problem.

Any suggestions and help would be appreciated!
