I think there is an unfortunate bug in the iOS version of the new iRecord app. I've just gone to upload my weekends records and it appears the app has logged me out and dumped all my stored records. Rather frustrating. It has logged me out a few times without warning and I suspected I've lost some records previously but this time has confirmed it.
Edit: I've just updated my iOS and I also noticed there is an app update too, so did that. Let's see if that's fixed the issue.
