Setting foldlevel has variable effects

[EricEWeir]

I have an iPad and an iPhone with iVim and vim-markdown. Identical .vimrc on both devices. In it I have let g:vim_markdown_folding_level = 6. I get different results on the two devices, neither satisfactory.

On the iPad headers with # fold but adjacent lines without #also fold. :verb set foldlevel reports foldlevel=3.

On the iPhone I get no holding in headers with # but adjacent lines without # do fold. :verb set foldlevel also reports foldlevel=3
