Function APP doesn't trigger on storage uploads

Azure function app stopped triggering on Storage uploads. We have two function apps:

It uses a Consumption Plan and Storage polling trigger and was working for quite some time. In the past week or so it practically stopped.

I am talking not about 10 minutes delay, but days and even weeks.

Both Function apps start processing new blobs when you access Log streaming or console.

The Consumption Plan of function apps makes cold start of the function execution. If you are using basic plans, you need to ensure the function is always warm. To do that, you can make use of a timer trigger function which makes the function in warm state always. Reference.
