After selecting 'Subscription' from your Profile dropdown, you are then able to see what your current subscription is, as well as an opportunity to 'Select' an alternate plan if you would like to change.  If you Select your current plan, it will simply return you to the main MoversPay screen.  If you are selecting to upgrade to the Premier plan from the Standard plan, you will be prompted to the next appropriate screens.
