More recent versions of the apple iPad have "private browsing" mode enabled on their Safari web browser. This has been known to cause issues with our website which is required to store small amounts of information on your iPad to operate correctly. "Private Browsing" prevents our site from doing this.
It is therefore highly recommended to turn off private browing on your iPad before accessing our sites.
Please follow the instructions provided by Apple at https://support.apple.com/en-gb/HT203036 to find out how to enable/disable private browsing.
