why is the screen lid doesn't close properly
whenever I close my MacBook Air m3 the lid doesn't close properly.Many suggested that's because I use a screen protector and a protective case
MacBook Air 13″, macOS 15.1
A screen protector is indeed the most likely culprit. Remove it and see if that fixes the issue. If not, try removing the case. Those are the easiest steps to try.
