I've also power-cycled the device, and that did not help either. I am actually running an older version of iOS, and so may go ahead and perform an update, just in case that might resolve the issue.
EVEN AFTER CLEARING HISTORY AND WEBSITE DATA IN SAFARI, I STILL CAN'T UPLOAD IMAGES TO IMGFLIP FROM MY PHONE; I TRIED IN CHROME, AND GOT THE SAME ISSUE, EVEN AFTER GRANTING CHROME ACCESS TO MY PHOTOS. CHROME ALSO WON'T LET ME MOVE OR ADJUST THE TEXT BOXES. ANY IDEAS?
