Aibu to expect the mumsnet app to work?

[Piggywiggywoo]

After carefully constructing a response to someone & ensuring proper punctuation, I discover the mumsnet app for iPhone has removed half the punctuation symbols and now it reads like gibberish. Pride aside comma I look like a rambling idiot (more so than usual). Aibu to expect an app for a site as popular as mumsnet to actually work?
