The Unity market place is full of alot of garbage and half of it you never know if its actually going to work or not until someone purchases it and then makes a post saying it does or not. It is a very very poor way of running a market place.
If as a creator you can not take the little time it takes to update your product then maybe your product shouldn’t be on the store selling then? Cause I maybe wrong but I do believe the marketplace terms state that as a marketplace seller you are responsible for updating your product. So having them delist products that are not being updated is a smart idea to me. Cause if your 30 mins of time can be spent updating your product then your product doesn’t need to be selling on the market place.
