Gradients not showing properly on Ios

Hi all, gradients on my Ios were showing fine up until almost one month ago. I don't know what happened but my shop went from looking like this: 

To now looking like this in Ios: 

I spoke with Shopify support but they said they cant help. They mentioned it to tech support and they will fix it one day or whatever that means.... I found another person who had this issue that used a line of code, here it is
When I enter it my shop looks like this: 

It also edits my header, can anyone tell me the solution to have my shop look on Ios exactly how it is on the mobile editor? Shopify support really can't help. Thank you!
