What mode are you editing your page in? Source, visual or rich-text?

That is, do you simply tap the "edit profile" button, or tap the arrow next to it and select "classic editor"? Also don't forget to preview your page before publishing. Sometimes the the changes don't show while typing and show up only after the page has been published.
