SEP Client unable to change locations automatically

Hello,

I am having an issue when my SEP client changes locations, it does not change automatically to the new policy created in SEPM. I have enabled location awareness in the policy general settings, and I have also enabled to Display the notification area icon. However, I am able to change locations manually by launching the SEP client and going into Change Settings > Configure Settings next to client management and change the location options, this picks up on the location policy instantly. The SEP client is running version12.1.4112.4156 and SEPM is running version 12.1.2015.2015. Assistance would be greatly appreciated.
