I have an iPhone 11 and was using safari to access trello. When I turn my screen from portrait to landscape, the power ups appear on the right hand side menu (like on a desktop). However, other iPhone users are not having the same experience. Their iPhones are slightly older generations.
Is it an iPhone generation issue? If so, what minimum version of the hardware do you need to have to have it work? If it's not a hardware issue, what else could it be?
