As a general rule, any page behind an Admin or Coach login will work best on Google Chrome, any page a Member can use we have to be a lot more lenient as to what they can use as its impossible to educate your members on which browser they can or can't use. The reason why we stick to Chrome for Admins and Coaches is because its currently the most advanced browser, and we do take advantage of some of these advanced features in certain areas. Its also the most popular browser, consistently having more than 50% market share. Most Control Panel features will work on other browsers, but not all, for this reason we recommend you stick with Chrome.
