Messenger box issue still persistent

The clunkyness of the messenger box still persist. It's been a problem for over a year yet never gets fixed. I am on the latest update and yet it keeps getting over looked. The message box needs to be pushed up more when the keyboard on mobile phones pops up and then needs to actually stick back to the bottom when not in use and scrolling. Most messenger apps don't have this issue and by now most people are used to a smooth easy messenger interface. If we want to persuade people to drop FB and other social media apps in favor of ours we need to make sure the experience is the same or superior. I understand messenger is going to have a new look and feel to it but PLEASE test it on mobile phones and your app FIRST before releasing it!
