Delayed Startup and Request Quota Metrics Incorrectly Show 100% Usage

[kakins]

I'm using the .NET SDK to work with Feature Flags in ASP.NET Core.

The first thing I noticed is that app configuration is loading extremely slow all of the sudden. My application hangs on this line provider.Load(), inside ConfigurationManager, presumably encountering some sort of throttle and/or retries when configuration from ACS is being fetched.

The method eventually completes, but this delayed behavior is causing my app service to timeout during startup in Azure.

However what I don't understand is why my requests would be throttled or even blocked. Here is my quota metric from my ACS instance -- where I am on the free tier with only one ACS instance in my subscription:

My understanding is I should get 1k requests/day. However, I am using far less than that. As you can see here I'm using about 150 requests per day.

And I have verified my connection string is valid multiple times.
