SAA "Duration" issue

Hi,

I’ve been a consistent SAA (beta) user for about a year. I find a lot of value in this app, in particular the charting, deficit tracking and the “soft alarm” features.

Unfortunately, SAA hasn’t been working properly for the past several days. The duration is way off, to the point of being unusable.

The figure shows an example of this on the left, with normal operation on the right.

I’m hoping it’s as simple as changing something in the settings. Please help, as I really like this app and would hate to uninstall it.

Thanks.

PS - I use the Mi Band 2 with Mi Band Tools as my wearable
