Intermittent "No job functions found."

I am getting following error on Azure intermittently, fix for me is to "Advanced Application restart" under diagnostic tools.

No job functions found. Try making your job classes and methods public. If you're using binding extensions (e.g. Azure Storage, ServiceBus, Timers, etc.) make sure you've called the registration method for the extension(s) in your startup code (e.g. builder.AddAzureStorage(), builder.AddServiceBus(), builder.AddTimers(), etc.)

I have to do perform "Advance Application restart" every couple of days and then something happens (maybe system maintenance / change of instance) and I see following messages in logs:

When application runs correctly I see 2 functions found (Custom) even though I have only 1 function defined. Even when I run the app locally it says 2 functions found (Custom).
