My Chime account is no longer working either. Had to use PayPal. The message I received on Chime's end was something like, "This platform does not support Chime or is from a country that does not support Chime." It was never an issue until this week, and I have international transactions turned on. I wonder if it's the same issue with Venmo, whatever the issue is.
I also have Chime and it wouldn't go through. I have a feeling it has to do with the holiday season and people claiming fraudulent charges. Chime must've said enough is enough and upped their standards. Curious to see if Sigil goes through when it's up for renewal. I went through Cash App and it was fine.
