I was using it a few years ago, but then I switched to Google Podcasts.

I will try it again, because Google Podcasts makes a "pop" sound notification every time it begins to download new episodes and it can't be turned off in the settings. It's very annoying.

Can't you use the Android system level notification settings? Many apps don't have any notification settings themselves, since Android provides them.
