• Component: Evangelism
• Status: NEW

[karl]

Browser / Version: Safari 13.1
Operating System: Mac OS X 10.15.4
Tested Another Browser: Yes Safari

Problem type: Site is not usable
Description: Browser unsupported
Steps to Reproduce:

Steps to reproduce.

1. Go to https://app.101edu.co/lti?lti=true

Expected:
Access the site

Actual:
Got the following message

"This browser is currently unsupported. Please use Chrome or Firefox for best results."

Diagnosis:

This is done by user agent detection.

The trigger is here. 

```js
export default function SupportedBrowserWall(props) {
    if (isSupported()) {
        return props.children;
    } else {
        return renderUnsupportedView();
    }
}
```

with 

```js
function isSupported() {
    if (OS != 'web') {
        return true;
    }

    let agent = window.navigator.userAgent;
    if (agent.indexOf("Version") != -1 && agent.indexOf("Safari") != -1) {
        return false;
    }
    return true;
}
```

Not sure what led them to block it.

rendering in safari

This is still happening in the latest version of STP 211.
With a fake Chrome UA, the login window is shown.
