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: ❌ Accessibility problems – some can’t read anything! Suggestion #1: Add pinch to zoom

Figure: 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!

Figure: Suggestion #2 is magic UX – see it is fixed
