Roon remote on Ipad can not find Roon Core

I have streamer, 432 Evo Aeon, which is my Roon Core. When I try to open Roon remote on my Ipad it says " You are already signed in". But I do not have another Roon Core. What is the problem? See picture,

Click the Unauthorized button and try to sign in again. Does that fix it?
