Ok I so I updated to this TERRIBLE update that doesnt allow you to copy and paste along with numerous other problems. It's actually kinda tragic because this is the only game I play on my phone and I love it.
But anyway I found a little way to still copy and paste even though the update doesn't really allow it due to the tabs messing everything up or wherever the problem is.

Ok in the first pic you can see that when you try to copy and paste the "Paste" button is just in front of the wall tab and it's not doing anything besides clicking on the wall tab.

Ok well in the second Pic you'll see that if you start clicking inside the "start typing to post a message" box that the "Paste" button moves from the top to the bottom. Once it's on the button you'll be able to actually click it and paste a message. Remember just keep clicking into the box until you see the paste button go to the bottom.

After doing that then your message should paste.
