Have you tried taking them off the dock, starting them from the home screen, seeing if they work there, then putting them back on the dock? Might be a location registration glitch in your iPhone.

Yes. The issue was only on iPad. And only on apps in the “recently used “right half of the dock. The apps won’t open from there. They will open off the dock as normal. Restarting the iPad solved the issue for about five minutes, then it happens again. It is only the apps that are in the recently used section of the dock that will not open while they are on the dock.

They work fine on my iPad Pro. . . Hmmmm, sounds like you’ve got a definite glitch issue that requires talking to Apple. One of those bugs that "affects some iPads . . ." You’ll see in a future bug fix update. Hey! Maybe you’ll get it attributed to you. Sorta like the fame of having a disease named after you. . .
