Download and use Puffin. It works for me on my iPad Air. I teach, and my curriclum runs on a website that is Flash-based. The ONLY way I have been able to get Apple and even some Galaxy Tabs to work on this website is with Puffin. It’s a bit wonky, granted, but it runs. Likewise with Google. My school district runs many of its functions through Google sites. Aside from my Google drive files, I can only access the other functions of the district’s Google site on Puffin. There are ways to get around some of the Apple-Google-Microsoft proprietary realms. Sometimes it doesn’t work as smoothly, but it’s better than nothing. Don’t get too tied down to Safari. It’s not often the right answer.
