Improve compatibility with VoiceOver feature on iPhone

[sbutkovi]

Testing 1.4.6 on an iPhone. When the VoiceOver feature is on, some of the features within the app work (reading text, navigating between most tabs), but some things do not work. Some of the notable things that don't work when VoiceOver is on:

• Selecting the "info" button in the lower-left of the landing page (when logged in)
• Opening chat on the landing page
• Trying to load any puzzle (it reads "Play Now" but there is no easy way to actually enter the puzzle)
• Actual puzzle gameplay

I also tried opening a puzzle, turning on VoiceOver, and heading back into the puzzle - upon the loading screen, I couldn't progress forward with VoiceOver on (but I did get a spoken message of "Select to enable accessibility for this content, button" when I swiped right off of the puzzle's title). And no puzzle gameplay appears to work.

Additionally, the in-puzzle screen kind of freezes if you had VoiceOver on, then turned it off and returned to the app. It's not truly frozen (I can see the bubbles moving), but I can't interact with anything on the screen.
