On every game hub, where you own the game, your playtime will be shown in the Mini Profile.

However, that currently only works if your overall playtime is public.
So that screenshot just shows me my own playtime, but it's not viewable publicly.

I'd like to recommend an additional setting. So your overall playtime can stay private.
The additional setting then would take care, that on the respective game hub, the Mini Profile will show the playtime (regardless of the overall setting).
