I’ve deployed a React website on Vercel and for some reason the css styling doesn’t get picked up on some devices but does on others. For example I tested the website on three different iPhone 13s and on two of them the website look as it should but on the third it looked nothing like it should. I realised that deviced has not picked up the css styling for some reason.

Has anyone come across this issue before and if so did you find a solution for it?

I tested this theory by applying the styling inline using style={{}} which worked. But I don’t want to have to do this for my whole website as this would take ages.
