Double tap your search filter (triangle on ps5) to refresh while bidding in the AH and see if it has been outbid by the small exclamation icon on the top right of the card. Use filters as needed with the amount of cards in the AH.
Auction house search window continually freezes for me though when i try using one of the number entries, the search pane goes blank and I have to restart the game.
Or if you try to bid very quickly the game can also crash as shown here: https://youtu.be/eNMugpCQ944?feature=shared
