Partial Android user cannot launch Secure Mail on desktop, error "This app requires a newer version of Secure Hub.Please update Secure Hub to run this app":

Besides, Secure Mail can be launched via Secure Hub.

Enable "Apps secondary launch" in Settings-> Permission manager -> Applications -> Secure Hub on Huawei Android phone:

Problem Cause

When Secure Mail is open on Home Screen, Secure Mail needs to call Secure Hub for VPN connection. If the "Apps secondary launch" setting is disable, Secure Mail cannot call Secure Hub.

When Secure Mail is open in Secure Hub, the call procedure is skipped thus it works well.
