If you encounter an error message similar to the one in the screenshot, a simple change in the settings of your device can remedy this problem. So far, it seems that this error only occurs when using an IOS device (Apple) with Safari web browser.
Three simple steps help to get rid of this error message:
1. Open the Settings App
2. Scroll down and click on the Safari icon
3. Scroll down and disable the "Prevent Cross-Site Tracking" switch (you can undo this once you downloaded the checklist)
