Question 1

On your mobile phone's browser, open the Menu section.

It will then show you a list of option, scroll down until you see something like "Desktop site" or "Desktop mode", enable it, then refresh the page.

You should then be able to see the page as if you are opening it thru your laptop. You'll then be able to see the Archive and Trash folder on the left side of your page. If not, you may want to rotate your form into landscape view to give the page wider area.
