Check if you got a text from the bank.
I tried to my card today and it got rejected, even though I entered everything correctly. Ended up using a different card. Then I noticed I got a text from the bank saying, “Did you attempt...Yes=1, No=2.” Entered 1 and got, “...Please retry. Your card is ready to use.”
About 20 years ago I used my credit card in a restaurant in Tampa. The next day, or the day after that, I got a phone call from VISA security asking if I had bought $1,000 worth of stereo equipment in New York City the day before. I told them no and they said, "We didn't think so". They cancelled that card and sent me a new one and the stereo equipment never showed up on my bill.
