Im having a similar issue. I’ve outlined it here.
I’m catching the webvitals for all merchants that use our app. the LCP from app bridge is well under the 2.5 average (hundereds of records captures a day) from the call back, but the partner dashboard shows otherwise.
Every other webvital score is well below the BFS standard.
The disconnect from app bridge to the partner dashboard or I am doing something really wrong. How do we resolve this?
