Wonder if its "choked" at the ground for security purposes?
Been to loads of venues recently and this has been the case Venue Cymru at the weekend, nothing inside unless on their wifi outside ok(wales is pretty poor so not a great example) But NEC, Bournemouth Pavillion, even the Derngate in Northants, could be just Tin Foil hat but seems to happen much more than it used ?
No idea like but minute of the ground all good!
