Manifest.xml is partially processed in Teams Admin panel leading to auth issue

Hi Teams dev community, we are facing a strange problem.


We have developed a simple application on Teams that opens a tab pointing to a private Webview (accessible only via our VPN).


When we deploy the manifest in our Teams test environment, the application works perfectly.


But when we deploy it in our production environment, the manifest is only partially taken into account.


We changed the UUID, upgraded the version number, but nothing works. The manifest is only partially taken into account, so the application does not appear, or sometimes it appears after several hours and there is a blank page on the front end and an invalid token error on the Msal backend (even though authentication works perfectly in our test environment).


On the web, we read about Teams policies that may be different, but IT tells us they have never touched the Teams policies.


Have you ever had this type of problem? Are there any tools to facilitate integration?


Thank you in advance for your help.
