On the 23rd of June, we became aware that some downloaded lessons fail to open.
If you're experiencing this, you will see the error message shown above.
Looks like your internet connection was lost.
Check your Wi-Fi options or switch to mobile data.
This is not an issue with your internet connection, naturally, you should be able to take downloaded lessons without an internet connection.
These lessons are still working normally while you're connected to the internet.
Thank you for your patience and understanding, we are currently working on a solution.
