Chatpad doesn't work correctly on Xbox Beta

Xbox One Better Together Beta:
When attempting to type in the chat using a chatpad on an Xbox One controller, the on-screen keyboard with occasionally drop down after every character, forcing me to reopen it for every character. The only way I have been able to fix this is by quitting and reopening the beta. As well as this, the chatpad usage in the chat, on signs, in a book and quill, and in anvils is not smooth. The on-screen keyboard must be opened every time to type and an unnecessary amount of buttons must be pushed just to type with the chatpad. It would be much nicer if, rather than the on-screen keyboard needing to be opened every time, that simply opening the chat, sign, book and quill, and anvil interfaces would allow the chatpad to be used, much more like how it works on the Xbox One Edition. Thank you!!
