Hi Thanks for reply, Actually i am using demo release build, And you can reproduce it every time by scrolling after selecting some authors on home screen, then that scrolling is not smooth on For You Screen and Saved Screen(after saving some items) , it stucks in between while scrolling

My device Model is Samsung Model name: Galaxy M31 Model Number: SM-M315F/DS Android Version: 12

Following are the attached logs while i was scrolling: now_in_android_logs.txt

Added more Jank tracking in #328. We'll have to continue investigating here.
