SideCar unstable in Monterey

Since upgrading to Monterey I find SideCar very unstable. Often when I try to connect it fails after a few seconds. If I retry enough times it usually eventually works, but even they after a while it spontaneously disconnects. I've also seen multiple times where my Mac seemed to think SideCar was still connected, but the SideCar display was not updating.

This used to work stably when I was running Big Sur. I'm also seeing this issue on two different Macs.

After update to latest Monterey 12.3 (Mac mini M1) and iPadOS 15.4 (iPad Pro 9.7") I couldn't see Sidecar / Screen Mirroring via USB, though iPad was recognized just fine on Mac. I had a few chats with support, glad I didn't proceeded with reinstalling macOS (as they suggested after a few other options weren't successful).

Solution, that came to my mind and did the trick was actually very simple:

>> Reseting trusted devices on iPad

About the 'Trust This Computer' alert on your iPhone, iPad or iPod touch – Apple Support (UK)

I assume there is some "handshake" problem after update (?) (whether on macOS or iPadOS, can't tell).

Hopefully it will help others (I will report this also on chat support to add this to their guidelines, before proposing to reinstall any of the devices).

Oh, and iPad Pro 12.9 first generation.

Can someone at Apple please fix this? Clearly it's a major issue, as well as a major selling point for iPads. I just purchased a brand new iPad Pro 12.9" and it doesn't work. Lets go folks.

Quick update: MacOS 12.2 and iPadOS 15.3 came out shortly after I posted my experiences with 12.1/15.2.1. Unfortunately, the OS updates do not address the issue, and the problem persists.

Hello,

Config:

Mac mini M1 2020

iPad Pro 2020

Internet connection from my Mac mini:

I have the same problem. It's unstable. I am not able to create the problem. it's random.

On the other hand, I am not able to create the problem. I thought it was my wireless network but I regularly do speed tests and signal strength checks.

When the problem occurs, the iPad "freezes" and subsequently registers that it is disconnected.

I also noticed that the Mac mini responded strangely. I had to forcibly turn it off (I know it's not the best way)

If not, good job ! :)

Thank you and have a nice day

Update.

I resolved the issue. I get the app Cisco from Apple Store.

I used to use the version automatically downloaded from my company

Unbelievable: my Ipad-on-Sidecar just froze on me.

Meaning: an update to iPad OS is certainly not enough
