Azure App Service Unloads during off peak usage hours Memory Working Set goes to 0 bytes

I have an app service (Azure Mobile App) that I just noticed seems to get unloaded when there are no active clients for a while--typically 5PM to 6AM.

It sometimes takes a few minutes for the service to "come alive" again when the first client of the day requests data, and that's not a good experience for that client.

How do I make sure it remains loaded/kept alive?

This is the Memory working set, Avg graph which is what clued me into thinking it's getting unloaded.

    This is known as cold start. Have you tried to set Always On on App Settings?
