Frontend not working on iphone

[zing-rsa]

The frontend produces a blank screen when opened on an iPhone.
Doesn't seem to be related to the browser used, reproduced on chrome and safari

Reproduce:

Open www.mern-social.zing-rsa.co.za on iphone

[zing-rsa]

Possible causes:

1. regex lookbehind used in singup for input validation, might not be supported on iphone
2. DNS not routing correctly, doubt this
   • browser error would usually be displayed
   • blank white screen is common symptom of runtime error in React/Javascript
