Probably a bit late but went through here on Saturday
Arrived T3, bussed in, clear signage to Transit.
There is a security check and they were rigorous on fluids... didnt see any duty free being confiscated but you should check..
Some people didnt seem to have onward boarding cards and were put on one side until they could be dealt with separately.
Past security signs for T2 or escallator up to T3
Allow 30 mins from start of security to gate in T3
Good luck!!
