Occasionally, with any browser-based application, it's important to clear your browser's history/cache/cookies. Sometimes settings can get stored, which then do not allow Kno2 to function as expected.
If this occurs, clearing the cache is a great first troubleshooting step. We've linked the instructions for browser clearing in many of the most popular browsers below. Like anything though, if you don't see your browser listed or the steps seem out of date - we're always happy to help. Just give us a shout!
