We did another round of guerrilla testing for VE on mobile today. Overall it was much improved from the last tests! 
Especially these changes: X icon to back icon, arrow icon to word "next", save page updates, and the switch between edit modes.

Here are those findings:
  • Used back button and it did what they expected
  • Hesitated when asked to save but all were able to find "Next" button
  • Filled out the save screen appropriately, although 1 person said it looked like an error screen at first
  • When asked to switch to wikitext, tapped gear icon almost immediately, but several people still struggled with "edit" and "edit source" language. Everyone also struggled with the pop-up asking them to save before switching. 
But the link and reference context bars really failed the user tests. :( Most did not notice that the icon in the toolbar was highlighted. Nobody even noticed the context bars, and didn't know what they meant when I pointed to them.

I would suggest we try adding blue links that say "edit link" and "edit citation" in those context bars, to show a user what they'll be doing specifically. The taller height will also make the bar more noticeable. Then we can test again!

Thanks,
