The lack of vWAN license stacking is crazy to me.
See here too: Please make vWAN Licenses stackable - #5 by AskTim
If I buy a vWAN license either specifically or by renewing primecare (which is non transferable) and then I buy another. I should now have the sum of those purchased vWANs available.
Anything else makes the end customer feel cheated and is impossible to defend.
