Hey! How are you loading Express in a native app? Are you using a Web view? Thanks, Logan ---

Hey there! I’m not exactly sure what is going on here. When I load the app in a browser on a phone the inputs appear just fine - this may be a bug with the WebView or something. If it just those specific inputs that dont work? ---

Yes, only “scale of measurement” is not working. ---
