IE is a very old browser and is not technically supported by AOPA products. We do our best to try to be compatible but there are many new web technologies that are simply not supported by IE browsers. There are also significant security issues with IE so anyone still using it should strongly consider other browsers.
Even Microsoft is moving away from their own browser rendering technology and moving to Chromium. They will retire Edge and release a new browser that uses the same underlying rendering engine as Chrome. So the new Microsoft browser (code named Anaheim) will render web pages the same as Chrome.
IE is notoriously incompatible with modern web apps. (I work for a software company, so I know whereof I speak.) Consider a different browser. (But not Edge -- it's no better!)
