How to avoid There Was a Problem Reaching This App Error When Launching Pinned App from Teams Desktop Client

Question

Starting ~2 weeks ago (around Sep 14th, 2021) many of our customers have started to report problems launching any PINNED apps from their desktop teams client. Web chat Teams client can launch pinned Apps fine. Apps are pinned as part of a set up policy in Teams Admin Portal, in this case a Global Set up Policy.

Jira App is shown below as an example but it is happening for all pinned aps, at least ones with a chat tab (bot).

If you click on the... below the app list on the left navigation rail and launch the app in that manner the error goes away.

The error does not prevent messaging to and from the app, just that it stop the users since they believe there is a problem. Clicking on retry does not do anything.

Are there any recent changes to Manifest files that may need to be addressed to avoid this pop over error?

Previous articles from Feb had recommended disabling Loading Indicator in Manifest files. That does not seem to have any impact on this situation.
