Can I refund where the original sale was made using multiple credit/debit cards?

Yes, you can refund a sale transaction where the payment was made using multiple credit or debit cards on the Clover Connect Payment Gateway. Since the payment was made using 2 separate credit cards, the application will prompt the cashier to specify the card to which the refund amount to be returned to. 
Plugins in Tagrain are either Subscription Based or License Based. So the price that you pay for your plugins is based on the number of POS terminals that you have in your setup and the number of licences that you have acquired.
There will be no change in your subscription amount in the current billing cycle if you are only deactivating the Clover Connect Payment Processor plugin AND not updating your Store / POS count. 
Activating or Deactivating the Clover Connect Payment Processor plugin will not affect your subscription amount for your next billing cycle because the plugin is free.
