They already provided one means of download, it's frowned upon to ask for another.
Besides, isn't a sharing link the most convenient means of download?
I’m on IOS too and have no issues clicking the Spaceflight simulator link above. It’s nice to use the sharing blueprint link because before it was a pain to add and move blueprints from .txt files and now it’s just one click.
Also I like how the engine looks Pickles the rocketier.
