I have a 12.9 iPad Pro M1 series and are an external thunderbolt four hub that was working perfectly fine seamlessly with all the things, the external hard drive, the monitor in fact, I had multiple monitors hooked up at one point everything was great I updated to 16.3.1 yesterday and since then I have had zero luck and stocks my monitor isn’t even get recognized whether it’s going through the hub or going straight through the device. There is definitely an issue with this update. Something has happened inside to remove the display port drivers or it’s done something wacky with the listing of the scripts, either way, this is a serious issue that Apple definitely needs to focus on and correct ASAP. I’ve used the HDMI adapter as well and it’s still not connecting. My stage manager never even comes up, so I really do think it has something to do with the DisplayPort drivers themselves, something must’ve been relocated or deleted or written over in some capacity, so Apple please get it together together and get a fix out, please 🙏 OK
