Open In App failure

Presently each attempt to follow a link which opens within a recognized app (today's example, a link to Twitter from Safari or Signal) will instead lead to the App Store, which was an appropriate step for an app which I did not already have loaded, but is improper process for an app I already have onboard, configured, and properly signed in.

If the question is about an app (Safari, Signal) and not your own code, you'd better contact Apple Support Community: https://discussions.apple.com/welcome
