AppleCard and AppleCash not working on Chicago's CTA (Ventra)

When I first received my AppleCard I was able to set it up, and get it to successfully work for tap-to-pay on Chicago's CTA. Then it stopped working and I would get an "Insufficient Funds" notice on the CTA's screens. I then switched to AppleCash. That also worked for awhile, but then similarly started saying I had insufficient funds. I am currently using my debit card via ApplePay just fine, and have been for a couple of months now.

My AppleCard is paid and current. I have plenty of AppleCash. My AppleCard is set as my primary and only card on my Ventra (CTA) account.

When I search, the only results I get are about using ApplePay (which works as long as I am using my debit card), but nothing helpful about the new AppleCard specifically.

Thanks,
