Patreon posted notices on Discord that there were issues with Payoneer, and they were working on them. Their last notice was that most of them had been resolved - but not yet all of them. It's possible itch.io faced the same Payoneer issues.
Still itchio made no comment about it, no announcement either, and they definitely did not reply to the support email sent to them from me. I think some accountability is needed here.
