The tracking on mine is still odd.
The Royal Mail number still isn't recognised, but the 4PX one just updated with entries for the 9th and today.
Going by usual 4PX parcels it should've been delivered today (three days following "customs cleared").
This is what's showing:
GBLONB / Arrive at the destination distribution center.
2023-10-11 01:46
LHR / Leave the overseas warehouse and prepare for transportation
2023-10-09 21:25
Released from customs: customs cleared.
2023-10-08 17:14
The latest event usually happens on the same day as customs clearance, and the one in the middle I don't ever remember seeing before.
The whole thing is as weird as the figure itself.
