How do you push updates of your app to your TestFlight testers?

Hey folks, first time getting to version 1.1 on TestFlight.

I received the email saying it was ready for internal testing but none of my three testers has received an email.

I also though unless you underwent a major version change (1.x to 2.x for example) that something small like 1.0 to 1.1 would be ready to go pretty quickly.

It says waiting for review, but I can’t recall if that’s waiting on tester review or Apple. If testers, then I’m missing a step.
