Hello and welcome!
I would gladly change your Airdrop membership to the WooCommerce gateway, but after your post, you also purchased subscription to the WooCommerce gateway. Does this mean that you plan to use both apps? Let me know how to proceed.
You can also email me about this if you like.
I will check my email later today, as I will be away from the weekend, back on Monday.
I will send your receipt after you let me know how to proceed.
with regards,
Alex
