My app is showing a black screen on some devices

Hi everyone,

I recently deployed my first app with Netlify. I shared the link to some friends for feedback. For most of them, everything works fine. But one gets a black (not blank) screen.
The background-colour of the app is black, so I assume that the components can not be rendered for some reason.

Has someone here an idea what I did wrong?

Many thanks in advance,

@emli This is the classic situation where you need more information.

You should ask the friend to visit any tool like https://www.whatsmybrowser.org, then copy the link and send it to you.

You could then do more targeted device/browser testing, instead of trying to guess what might be wrong.

Tooling like https://www.browserstack.com can be used to test specific combinations of device and browser.
