They can open nearly instantly, but they need to be well-built native apps. Lumbering behemoths like Adobe CC or anything Chrome-based is going to be a bit slow, and even smaller apps that pull in a big foreign UI toolkit are going to take a tick or two longer to start.

It’s too bad that the art of building lightweight applications is becoming a lost art.

same with iphones and switching between cellular and wifi connections. I'll be walking away from or toward my home or my office and there's just barely a wifi connection, but hardly enough for any requests or responses to even make it through, yet Apple never allows the phone to fall back toward the cellular connection.

I can't believe in all these years they haven't implemented a dual setup where they connect the wifi and do some kind of test connection or request to confirm it's a stable signal before entirely switching away from cellular data.

Maybe you’ve turned off WiFi Assist? It’s an option to allow mobile data to supplement WiFi.

Nope. it's enabled.

That's the thing. I think parent question should have been the opposite.

If it's enabled, it tries as hard as can be to 'assist', even if the Wifi is bad, and it should have given up a long time ago.

On the current M series hardware, in my experience, it's rare for the icon to land from its first bounce before the software is up and ready.
