Winamax seemed to let me in ok this morning...
Some sites - not suggesting this is the case here - are not making the changes until Monday.
The GC have, sensibly, accepted that a Saturday is a really bad day to have to make wholesale changes, & especially - in every case for UK facing sites - get players to formally acknowledge the new T & C's, so the GC have allowed the date to move back to Monday 3rd November.
Please don't take this as gospel, but I know it to be true in the case of numerous sites.
Amazingly, Unibet Customers will face a 2 hour scheduled site closure @ 7am on Monday to allow the changes to be made. Not sure I understand why, as all the necessary changes can be pre-prepared, & then the cat-flop opened when the time comes, but no doubt there is good reason.
