After installing and opening the app, users see the message App Not Authorized, even though the .mdx file is on the XenMobile Server.
This issue can happen if users install the app directly from the App Store or Google Play and Secure Hub is not refreshed. Secure Hub needs to be refreshed when the inactivity timer is expired. Policies refresh when users opens Secure Hub and reauthenticate. The app is authorized the next time users open the app.
Today I figure out another issue when even after I authorized the app, it loops standing that the app need to be authorized.
I made some research, testing deleting and recreating the App in the Store with no chance.
At the end, the solution I found, thinking that it could be a lock in the DB, was to restart my DB server and my XMS Nodes.
After doing that, I was able to successfully open the Secure App.
