Bug with Classic Group Finder Feature

Hello, I have the latest Extantion and an active sub.
Today i tryed to use the Group Finder feature in Wow Classic, but i think there is a bug, when trying to make full use of it, i was asked to either give my phone number or install blizard spyware on my phone. This is definitly a bug right ? I’m paying and as a customer i’m being treated like some F2P moblie gacha player ?

I believe this bug should be adressed.
