Patreon is back at it. Check this out if you have problems with your membership (Patreon)

Patreon is filling that fuck-up quota for the year and, as always, they are too shy to contact patrons directly. At least not to my knowledge.

In short, if your membership is not working, Patreon recommends checking your payment method. Check out the screenshot for the exact menu. If it's correct, but the payment doesn't go through, Patreon recommends calling your bank to confirm that you want your Patreon payment to go through.
