Flickering Screen on Vinted app

Hi. Has anyone had any issues with Vinted app. I’ve seen some conversations about certain apps causing this but mine is only on vinted.

it’s worse if I’m trying to get a QR code to send something as the screen brightens it happens everytime but can intermittently do it other times whilst on the app. This continues after I come off the app and only stops if I swipe it off my screen to close the app completely
