Hey
i am send you a new apk file where the text merging issue will be resolved.
For the video in app you have to add this shortcode
[iframevideo]<iframe src='https://www.youtube.com/embed/MFtX9ussRKk' width='560' height='315' frameborder='0' allowfullscreen=''></iframe>[/iframevideo]
And also set unit type to video then the video will be working properly.
