I missed the bit where it went 64-bit, but it does indeed work on iOS 15.6.1, which is cool, thanks!
BTW is there a way to zoom other than turning the iPhone/iPad into portrait orientation? (It really doesn't scroll sideways nicely BTW. Oh and yes I get that's just the way it is, I'm just happy it's back.)
Works when running on an iPad connected to an external 4k monitor (Thunderbolt 3 via USB-C). (I had to down-size the images to meet the 2560 pixel forum limit....)

P.S. Posting in the Windows forum as I couldn't find an iOS forum and other iOS posts are here...

I am rocking it on my iPhone 15 Pro Max, and it still looks gorgeous. iOS 17.1.

Be nice if they could make a version that would run on CarPlay.
