My online BT usage hasn't been changed since the 28th September so I have no idea if I have gone over the allowance. I can't find any evidence of a new usage monitor. If there is a new monitor iI would have thought BT would have emailed or put a note on its monitor web page to that end.
It's happenening every weekend. The forum moderators are looking into it and will post an update when they have one.
Just tried mine again, updated to 30th September. It really isn't good enough, if I had gone over my limit I expect I would have been charged another £5!
the usage meter updates a day in arrears during today it will update to show October the 1st
It was stuck on the 28th for me all over the weekend. It wasn't until Monday that it updated itself.
