Update I’ve also tried disabling all of my plug-ins but still saw the same issue. I should also, mention that when one of my sites become unavailable, a second site of mine also becomes unavailable. They are on a common server, however they each have their own url, directory, and database. The second site is not even configured for use with the mobile apps. I should also mention that I was also able to recreate the issue using the app for the Kindle Fire.
