You can change the font in GatherContent, which affects the typing font - so anything you see in editable text fields.
To do this:
1. Click your avatar at the top right of the page.
2. Open your 'Personal Settings'.
3. Click the 'Accessibility' tab
4. Change the font in the dropdown to your preferred font
5. Changes are automatically saved once you select it. You should see a confirmation message 'Changes applied' below.
Navigate to an item, and you should see the font inside text fields has changed 👍
This change affects your account view only. So this must be set for each user individually.
