I am trying to install a new instance of pwa with Magento 2.3.1 I am using Magento's cloud setup URL provided by default in my .env file. I get my build successful and the URLs are generated correctly but could not open the link in browser. It hangs at "Loading Homepage content..." text. I could see below error repeatedly thrown in my browser console.

react-dom.development.js?e595:506 Warning: Encountered two children with the same key, 'ReferenceError13H'. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.

I have checked with multiple install of Magento as well as pwa-studio with no success.

Looks like it's browser compatibility issue. Please try to check it in different browsers, also please update your current browser.
