Just tried on my iPad min and it worked fine, creating icon on home page.
I typed http://www.modelboats.co.uk/app into browser, found site, it was about 5th down, opened it, it asks for email address + password (subscriber) and then followed normal iPad operating system procedure for putting icon on to desktop – which works. I did NOT copyand paste the address.
You do only get the digital issues free if you are a registered subscriber though.
If not, then digital issues can be bought via iTunes/Newstand – just type model boats in to the search facility.
H/O is now closed until Jan 2nd, so not possible to ask anyone there to resolve further.
I cannot comment on other tablet/phone operating systems as Apple is all I have.
