iPhone XR issues – 30 Day - Plank Challenge Review

On my previous iPhone, when I downloaded the app, I had no problems. Now with iPhone XR, the app is too big for the screen, and I can’t use it for my challenges. It only shows 4 days in a row, starts at day 2-5, and continues, Please fix this soon! I love love this app!
