There are accessibility problems.
E.g. I am having some of the 50 year olds in SSW reporting that they cannot even use the SharePoint app.
Reason – they can’t read anything!
Suggestion #1: below
Suggestion #2: below

Note: it is not only the SharePoint app

❌ Same issue on the Dynamics app

✅ The Teams app has fixed this issue

✅ The Outlook app has fixed this issue

Figure: Android default is too hard to read for some.

Suggestion #1: Fix this accessibility problem by adding pinch to zoom (users expect the same as the web page)

Figure: Android Settings

Suggestion #2 – add a Cogs button that would take the user to Settings | Font Size and Style where they can increase the system font size! People don’t want to use this setting because it changes everything on your phone.

Figure: Android after increasing the size on Settings

Suggestion #2 is magic UX – see it is broadly fixed (❌ the top “News” is weird)

iOS seems to have a different problem

Figure: iOS normal view

Figure: iOS accessibility settings

Figure: ❌ Broken – Nothing increased except for the Search box (which is overlapping)
