Dawn 15.3.0 - Website crashes on Iphone?

Shopify Discussion

Topic summary

A Shopify store owner encountered a critical issue where their website crashed exclusively on iPhones, displaying a repeated error message, while functioning normally on desktop and Android devices. Shopify support found no backend issues.

Root Cause Identified:

  • The website was loading approximately 55MB of data on iPhones
  • This excessive size caused Apple devices to crash during page load
  • Android devices handled the same content without problems

Resolution:

  • Compressed images across the site
  • Website now loads successfully on iPhones
  • Issue appears to be resolved

This highlights a platform-specific performance threshold where iOS devices are more sensitive to large page sizes than Android.

Hi All. I need some help and I can not figure it out. I have gone live with my website and all is working well on desktop and Android phones BUT The website crashes and tries to reload and then shows "a problem occurred repeatedly on (URL). I spoke with Shopify support and they can not see any issues there end.

I deleted cookies and data on iphone but it still does now load the website. I have even asked my family members and it turns out one android user is fine seeing the website but those family members with Apple phones get the crashed message!

I am clueless and need to figure out why and then fix it so customers on iphone can go to website!

Hello. Update for this thread. It turns out we figured out the problem. Funnily enough it was do with the website size for Iphones/Apple to run although Androids worked perfectly. The website data on Iphone was showing around 55MB upon website loading so therefore we compressed images on the site and it now seems to be working.
