The speed tests we ask you to provide will help us understand if your connection is meeting the requirements to maintain a call on Cambly. If we require this information from you we will ask you to complete a test here: https://speedof.me/ and then send in a screenshot of the results.
Make sure that you have the Console menu selected at the top of your panel and not the others (Elements).
WARNING: A Cambly staff member will NOT tell you to paste text into your JS console. This is one method of how malicious firmware is downloaded onto computers.
