For some reason, Last interval power target didn’t change (kept prior interval power), please see the picture attached
I didn’t change the power target with the Arrow Up key on the screen
It’s a special feature that if it knows you have not been training enough it makes the workout harder 
No really, we believe we know what causes this, what we don’t know is how other apps deal with it. Meaning some times trainers throw errors but we are not seeing the error but we should automatically try to set the target again. We used to have a different solution for this, the problem is that solution caused issues to some specific devices… so long story. The next version of our app has a mild fix for this, and if the mild fix does not completely solve it 100% of the time we will find a more intense fix.
