Confirmed. The 6 hour rule hit me. But no major hassle. Entered using egate instead of spending what looked like a long time in the "Fast" lane. Upon exit, when the card didn't work I just went to the counter straight away. Much faster than all those times that I spend trying 15 times to go through egates which don't work and end up at the counter anyway.

As long as that doesn't preclude me from using egates at my next entry (maybe there is some logic by which you can only enter through egates after having left through egates) I'm fine.
