I currently have 4 subscriptions. Two of which are level 1, and two are level 2.
The level 1 are similar in access, but are package A Monthly vs package C Yearly,
While the Level 2 are premium package B Month vs package D Yearly.
How does this effect Upgrade and or downgrade?
Basically I want upgrade to be immediate, and downgrade, at the end of the cycle.
For instance, each package increases in A, to B to C to D. If someone moves from A to B or from B to C he pays the difference, and upgrades, alternatively if he moves from D to C or C to B he will wait until the end of the cycle and move.
How can that be changed? Is the change immediate?
