This has been a weekly event for a couple of months. I've just asked the mods for info.
I looked at the Usage at about 4 o'clock this afternoon (25th Sept) and it displayed the usage upto the 23rd September and I have just looked again at 22:25 this evening and it is showing upto 23:59 on the 24th, so perahaps they are now catching up.
I've got a feeling I read somewhere that it updates at 0730, so not long to wait
Anyone else get the message that the monitor is undergoing maintenance and to try again later? Have had this for several days now.
