While I do my best to format lessons so that they display well on all devices and computers, this isn't always the case.
The most common issue is your mobile device. You might try reading the emails via a different device (so if you're on mobile, try reading them on a laptop. If you're on a laptop, try a different internet browser).
If you are still having trouble viewing the lessons, please feel free to contact us via the Help Desk so we can look into the issue. Please describe the issue in detail, and include any additional information you can about the email provider you use and what kind of computer and browser you are using. This will help us investigate further.
