Game Chat Problem in Android App

I was recently trying to share percentages with an opponent, during a chess game and I noticed that I was unable to get the percentage sign to show up, after I hit the enter button. It is there, after you type it, but not after you hit enter. I will assume there is a conflict in the code, over the use of the percent sign, for the code itself. I could try sending a pic, but it is hard to take a pic of something that won't show after I hit the enter key. 

Which version of the app are you using?

v3.7.3-19683

I can't even find the enter button for ingame chat, my opponent's must think I'm a right ignoramus 

We're working on this! Sorry for trouble! 

I appreciate it. It isn't a terrible inconvenience at this point, but thought maybe it was part of a larger problem that I don't see all of.
