Hi, sorry to hear that you're having issues. I tried this on locally running yarn start and setting app.baseUrl to http://0.0.0.0:3000 to get it to listen on all interfaces. I have no problems reaching the site on my iPhone.

I believe this may be related to #6039 . It will happen in all browsers on those devices since they are all forced to use the same underlying system web view component, if I recall correctly.

I managed to reproduce this on master and also purging yarn.lock. It's the same problem on Safari on Mac so freben is right that it's related to the issue linked.

Trying to put in place the (probably partial) fix proposed in the comment in that linked ticket: #8132

I'll close this as a duplicate, but thanks for reporting and it'll stay pointed to through the references in the "main" ticket.
