Here's what you should do if you are experiencing issues accessing content within your Sketchy account. . .
Oh no! Let's work this out.
We recommend using the Chrome browser to access Sketchy content if you are experiencing any test or video errors. If the Chrome browser is already being used, we recommend clearing your browser cache. The steps to do this can be found in our Help Center article titled, "Reset Broswer Cache". This works for most users.
If the issue persists, please let us know which specific content lessons/subjects are producing the error for you by contacting us at support@sketchy.com.
