Unavoidably we do have relatively long App name, but it is not displayed in a fancy way at the moment. Sorry for Appsheet team, I would say this is a bug.
See the result of inspection.
Obviously, the width of text area (h3 tag) is set wider than the width of side bar navigation. Then it always cuts off the rest of App name when it is long enough to go beyond the length of side bar navigation.
@morgan sorry Morgan, I need to make you more busy.
