Fail.
Ford just tried an update, said they saw nothing available. Last updates showing as occurred on my build day. Which means truck never received an OTA update in ~20 months since build date.
Then the OTA team gave me a TSB (22-2404) and an email to someone at corporate if dealer says it cant be updated again.
@rugedraw on the other forum had this to say. I guess I am just special, fellas.

Very strange. Your truck has never received an OTA, yet you are at Sync 22136 which is supposed to be past the bad software version where 2021 trucks are known to get stuck.
Your dealer connected your truck to FDRS, but never attempted to update anything. For sure there are updates pending for your truck. I don't have a good answer as to why you have never gotten an update. It can't be a coincidence. Something has to be wrong."
