Sign Bug (MCPE)

When you place a sign inside of MCPE Kindle Fire, The Normal "> <" does not show up, along with text. The only sign of text showing up is when you press Enter/Return on Line 3 or 4 the text will show up. If you type the text in (while text not visible) and exit the sign the text will show up. I couldn't find where to report MCPE Bugs, move this to MCPE Bugs if you are a Moderator please.
