App Service autoscaling behaves strange recently. I have scaling rules set up based on time of day.
I can not set up overlapping rules, for example rule A: from 08:00 till 11:00, rule B: from 11:00 till 14:00. After saving this rules are automatically converted to A: 08:00 till 10:59 and B: 11:00 till 14:00.
Then autoscaling probe runs on 10:59 and decides that there is no applicable rule and scales everything down (using default rule). And on 11:00 it finds applicable rule B and scales everything up again.
I am pretty sure it just started to happen few days ago. Before everything was fine. Any advice how to prevent autoscaling to fallback to default autoscale rule between rules A and B?
