Symbol files NOT being uploaded automatically?

Are we supposed to upload symbols file manually or are they uploaded automatically?

Reading this from your documentation :
When you build a project on which crash and exception reporting is enabled, Unity generates a symbol file and uploads it to the crash and exception reporting servers. If the process fails, the symbols missing message appears in the Services Dashboard.

My crash reporting is on (see the attached screenshot)

But unless I manually upload file here:

I don’t see my latest build Symbols file?

I do have Create Symbols File enabled in the build setting:

and I can see that file IS getting created in the build folder…
So can somebody please explain what am I missing?

It’s just this is something that could potentially save a lot of time when you have to do 10+ builds in a day, if we DON’T have to do it manually , or if we do, perhaps then we can turn it off in the build process as that slows down each build considerably… OR are these 2 separate servers then? Which one is used for Crash reporting then? It’s just so very confusing!
