Missed flight because Lyft

I just missed a flight because Lyft on my iPhone turned up its nose at my credit card, saying ...



I entered the information Lyft asked for, it thanked me ... and then sent me back to the same screen when I attempted to get a ride. 



I tried changing the credit card Lyft used.  No good, same message.



I called the credit card company.  No problem on their end.



It looks like Lyft may be doing their own fraud monitoring. Lyft may have noticed transactions from out of country. This is an issue, since I alerted my credit card company as to my travel, but not Lyft, or similar companies.  Not to mention the privacy issue, if Lyft is monitoring my credit card transactions.



Lyft tech support?  What's that?
