It can be done. If you are using the app, go to the bottom of the page and there are a couple of links. One of them is "Classic site", click on that and it will (should) work exactly the same as if it were a PC only smaller. hehe

I'd tell them this - it takes just as much time to educate than it does to threaten with an ultimatum/neg, and one will have a much better result for everyone.

Telling or showing people things they don't know is always the better option. 😉
