Log Progress: Ability to add decimal value

I have a habit for “Sleep for 7 hours” and I want to log 6.5 hours, but I can only log 6 hours or 7 hours. Can’t enter decimals in the mobile app and on the web app when I enter 6.5, only 6 is considered. I’d imagine it would be easy to allow decimal entries for habits and not sure if this is by design or a bug.
