I leave dry food out all the time.
They used to get half a pouch of wet food twice a day as wel;, but this has reduced to one pouch split between 3 once a day.
Evie was getting chubby, and Dexter has had dental problems and wet food is worse for this apparently. And Denzel just licks the gravy off anyway.....
My vets is not keen on wet food
as it is so much more calorific than dry.
I know there are pros and cons for both.
I would reduce the amount and try and give them plenty of playtime if they are indoors only.
