I requalified for Gold back in October or November.
In February, I called UA because I didn't receive a new card with new expiration date. I got denied entry at 3 different Star Alliance lounges(including LH) because I didn't have a new card with new expiration date. They would not accept the virtual card on the United app.
Of course, I didn't get the card that the agent supposedly requested for me. I called two more times during late February and March. Still nothing.
This week. I received 4 cards in different envelopes all within 5 days. Don't know if UA or the post office is to blame for this.
