We have just become aware that the video link service provider we use for our unit study products has been hacked. As a result, the video service provider is suffering a variety of technical issues, including unwanted redirect of Internet links on mobile devices.
PLEASE USE OUR PRODUCTS ONLY ON DESKTOP OR LAPTOP COMPUTERS, NOT MOBILE DEVICES (i.e. cell phones or tablets, Kindle Fire, etc.), until we notify you that our video filtering service has corrected these technical problems. Again: the problem does not occur on desktop or laptop computers.
Also, as we say in each study, please take a few minutes to check the links before your child uses them.
Thank you for your patience and understanding.
