Why do our users keep being ask to activate during the day sometimes multiple times per session.

We are currently having an issue with Activation. Sometimes our users will be asked to activate Adobe multiple times during a session.

We are running a Citrix XenDesktop environment and have about 10 people using Adobe in this server. The server is non persistent so after every reboot all configuration is wiped. AppData is redirected per user, so If a setting is saved there it will be available the next time they sign in.
