Does my browser affect performance of the system?

Absolutely, more than you'd think. 

The system will not work as well or look as good on older versions of browsers. 

Make sure that you are using the most current version of your browser. 

Internet Explorer is NOT supported (Since IE hasn't been supported by Microsoft since 2014, it doesn't play well with many websites, including CoachAccountable.)

If you are currently using Internet Explorer, consider switching to Firefox or Chrome. If you're committed to using Microsoft products, please change to Microsoft Edge, which is the current browser.
