Just to answer your earlier questions. I have never had any post of any length cut off. I've posted plenty of long posts with Tapatalk. I'm currently on my Moto E. It's my preferred method of browsing the forum. I also use my Nexus 7 but for typing long posts I use my phone which for me is easier to type on.
Somethings that do not work in Tapatalk is polls and code tags. Some emotes will not work you will only see the code for them such as
it doesn't work.
