Hi all. I used my reader to start my new sensor at work, then later scanned with my phone. All was well (apart from a hypo) until i accidentally scanned my old sensor by mistake (i leave it on until i get home). I have done this before on occasion and it usually tells me that its ended. However, today it didnt and when i scanned the right sensor, it shows a time zone change and isn't showing a good chunk of my graph. The logbook is ok though. Any ideas as to what has happened or whether i've done something would be appreciated. Thanks.
