New 2025 Air GT - just delivered - Homelink fails to communicate with garage receiver - Help?

[JerseyDavis]

My case appears to be different from those here in that the signal records properly, but then Homelink fails its tests.

I got my new Air GT yesterday. Yay. I have tried the following to get Homelink to work:

1. Simply followed instructions. The car honks/flashes lights and records the signal. Then it fails to communicate with the garage receiver (which is less than 10 feet away). Repeated this 4 times. Same fail.
2. Called the Lucid customer service number. Guy said try the reset (#3), and if that doesn't work he can't help.
3. Did a soft reset (X + mic + brake). Then repeated above sequence. Records the signal, fails to communicate with receiver. Just as every time defore.

--I have a Genie Pro (maybe 15 years old, programmed fine with 3 other cars in last 5 years, including a Tesla). The learning button flashes properly when pushed & lasts the 30 seconds. It is still paired just fine with my other car (Lexus).

--I move the car where the front is under the receiver and also just in front of the receiver. No difference.

--Every press of my remote operates the door without fail (and I have 2 remotes, tried them both, they work fine, Lucid recognizes a signal from either one)

Any ideas people? I fear that customer service number will be of no further use in this issue.
