Users can currently only edit by section, with only the top (lead) section edit icon visible at first, since edit icons for each subsequent H2 section are only visible in the header when the section is expanded, and all sections are closed by default.
This is potentially a problem newcomers shown guidance (on the read-mode SE footer) advising them to tap on the edit pencil icon to start editing on first arriving on the page. This, combined with the pulsing blue dot on that first edit pencil only may result in users being confused about how to edit subsections.
Update the read-mode footer text on mobile to include a note about needing to edit by section.
Proposed copy update:
Ready? Open the section you want to edit and tap the pencil icon.
