iOS not updating viewport size immediately on orientation change, viewport stretched

I also encountered this problem, I had to upgrade unreal5.1 in order to upload to the appstore, and I wanted to avoid this problem by using unreal5.0, but I couldn’t upload to the appstore
我也遇到了这个问题,我为了上传到appstore必须升级unreal5.1,想避开这个问题就要用unreal5.0,但上传不了appstore
