Website loads extremely slow in mobile safari but fine in Chrome

Website loads extremely slow in safari but fine in Firefox even with cache etc.

Can be very intermittent – sometimes works but very slow on Safari – I check on my iPhone 7.

Computer and desktop are lightening fast – I have cache and other performance settings set via plugins and Cloudflare.

I study my analytics and want notice a lot of iPhone users accessing the site but worry they are getting a bad experience compared to others.

Thanks

Paul
