Why is Merlyn opening in a different browser?

Merlyn requires you to use either Chrome or Edge, so you will want to verify one of those is set as your default browser for your computer. 

To check your default browser: 

Mac

1. Open System Preferences.

2. Select "Desktop & Dock" from the left side menu. 

3. Scroll down to the "Widgets" section and select either Google Chrome or Microsoft Edge from the Default web browser drop-down. 

4. Your selection will save automatically!  

Windows

1. Select Start > Settings > Apps > Default apps.

2. Open Default apps.

3. Select Google Chrome or Microsoft Edge.

4. Click on "Set default"
