Do you actually get a text message on your phone which states: 5b? What is your tracker showing when you get the text? Mine only shows In transit and I haven't received any text message since it jumped from stage 4 to 5.
Yes I got a text saying it had gone to 5a on the 15th and tracker stated 4 weeks on avg from now, then 3 days later 5b (18th) and tracker stated 3 weeks on avg from now.
It actually says "...has progressed to stage 5b of 7 (in transit: shipping)."
It has updated 3 times on a Sunday at about 8.30am so here is hoping this Sunday is no different.
