Okay, I retract my post!
@self Just seen it, it's a very small amount and seems to be wiped out when you next bolus, that's probably why I hadn't seen it. I just had to correct for a very slight amount 6hrs post my meal... On the pump clock I was late by about 6 mins and my correction showed IOB of 0.09u.
I'm guessing it's a software issue which could be fixed via a patch but I doubt they are able to reproduce it. I'll let others know about this and see if we can get some answers
Ingrid, thanks for sticking with it, least I know that is what is going on. Still trying to rack my brain if this was brought up during training as there was little snippets of info that weren't relevant at the time.
