Uploading ios app to app store

I’ve been banging my head against the keyboard for the past two days trying to upload my app to the app store.

I have all the bundle id’s set to the same value in Itunes connect, xcode and my apple developer certificates page but when I try to upload the app in xcode I get an error message: “Bundle ID not found”

Has anyone come across this before?

I had dozens of confusing things to figure out, but that wasn’t one of them for me, thankfully.

I hope you got it figured out?
