Ballot using Amex

Interested to know if anyone has won the ballot (think they introduced it first for Bayern) using Amex? Not had the pre auth show up for Bayern or Bournemouth…Arsenal showing I’ve entered but interested to know if there’s a chance the payment doesn’t work because of this?

Also, have peopled had much luck on Villa TX? Crazy how much harder it’s got throughout the season, even with restricted use!
