Are you having trouble processing payment? (Patreon)

There seems to be an issue with Patreon at the moment(it was starting since last month in fact) that some patrons can't process payment with their card. 

Since last month, my revenue dropped like $600-ish. I thought it was because my content is not up to satisfactory and people decided to dropped their support. But now it seems a lot of creator losses their patrons and from what we gather it some kind of botched transaction process between bank and Patreon

So is this true? I want to know how many people encounter this issue.
