Sometimes it may be required to clear your cache & cookies so that your TrackR dashboard can load up properly. All web browsers save cookies in a form of files into an area of your computer called "cache" which helps speed up your web browser as it remembers every time you re-enter that site again.
However, if these temporary files have not been cleared for a very long time and there are a lot of them, it takes up your computer hard disk space and computer power, slowing it down every time you browse the web.
It is also good practice to clear your cache & cookies every now and then for better security so that your browser is cleared of cached information, and it will work better when it's not loaded with old files that you may not need anymore.
