Hi Pangwen,
Great summary. Indeed any member with a pro-rate amount below $20 was rounded up to $20.
In your case, the offer is indeed not reoccurring as the one for Zig. As you mentioned, you have the option to renew your Gold membership now with a $20 credit for $55 for the next 12 months, or wait until May 2024 when you automatically drop back to a basic membership. At that point you can manually upgrade to Gold for $75.
In summary, as requested by the community we provide an opportunity now to swap to Stripe in a simple few clicks so you don't have worry about your membership expiring next year, while making sure that reoccurring special offers and membership credits are honoured. Each members is definitely welcome to upgrade their account on their own accord after the expiry date.
It's not an easy task to help our members move between payment systems, so your support and patience is very much appreciated.
