Latest beta 4 and no sign of it working between an intel macbook pro and M1 iPad. If it now works between M1 macs and iPads it's kind of weird that they're still no mentions of it in the release notes unless I'm missing something.

Coincidentally, I've just started to venture into this and I'm having a hard time finding a native component that would alleviate a lot of the boilerplate stuff. I'm now looking further into just loading a webview and a js library which I think would be a lot easier.
