If your classroom isn’t loading, try reloading the page! It can sometimes get stuck depending on your connection, so giving it a quick refresh can often give it the boost it needs to get started.
If this doesn’t work, it’s best to ensure you are using the correct browser on the correct device! The classroom is most compatible with either Google Chrome or Mozilla Firefox, and users trying to use other browsers such as Internet Explorer, Safari, or Microsoft Edge will commonly have issues with the classroom leading on our website. Please also ensure you are using a laptop or computer, as the classroom unfortunately won't run on a tablet or mobile phone.
If you have any ad-blockers or a strong antivirus system in place this can also prevent the classroom from opening - try turning these off if you do have them running in the background and reloading the page.
