For the last week or so the reply box is Donald Ducked for me on my phone. Not the easiest to explain but I'll try. When I'm typing the suggested words are not appearing all the time so I have to go back and type them. I'm getting problems such as the word not correcting or the first letter appearing at the end of the word ive just typed. For example: The text box is completely fucked please save my life. Is coming out as: TheTyexy box isia completlycofucked please savesmy lifel. And no that last line isnt made up, SwiftKey usually corrects my typing very well.
Weirdly I've just turned off the Rich Text Editor setting and it's working perfectly now. I can check chat later as well. It was updated on the 1st, I'll find another website that has Rich Text editing for you.
Maybe it workes better with another one,looks like SwiftKey is guilty. just typed that with Google one and it works perfect.
