Hi, it takes very long to load supermetrics. i can't even go past the launch screen, and not forgeting about refreshing all the preset queries
I would like you to try two things to sort out what's causing this.
1.) Try to open Supermetrics with a different browser
2.) If you have access to any other google account, log in with that, install Supermetrics sidebar to that profile from here and test the functionality.
Thank you for your help in this matter.
