Redirect 301 is not working. Trying to retain brand authority

Hello,

I've set up a redirect as followed: https://app.tutoringprof.com -> https://install.page/tutoringprof 301

When you go to app.tutoringprof.com it does not redirect successfully. What am I doing wrong? My records are all hosted and managed by Squarespace. These records exist within tutoringprof.com domain. Do I need to set these same records in app.tutoringprof.com?

The end goal here is retain brand authority so we created a sub domain for the the mobile app install to then redirect to the third party site for installation
