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 solve the issue, it’s best to ensure you are using the correct browser on the correct device! The classroom is most compatible with Google Chrome, so please do use these where possible! Please also ensure you are using a laptop or computer.
You can read more about recommended set up and browsers here and improving your internet connection here.
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.
A good tip is to also go into incognito mode when in Google Chrome, as sometimes the build up of the cache on your browser can lead to the classroom not loading normally. To do this, you just need to click on the three dots in the top right hand corner of Google Chrome, and then select 'New Incognito Window' - you can then go through to the site and your account as normal, and access the classroom!
If you're still unable to load up the classroom, it is worth trying shutting down your device down and turning it on again, or alternatively, try accessing it on a different device.
