Finding 12 testers was a struggle for my app [1]. Had to use a mix of LinkedIn begging, work colleagues, friends, and people from random Whatsapp groups I was in.

Once you get over that hurdle for your first release, at least you don't have to do it for every update.

The Play Console is a bit fiddly and I'm always getting random warnings that I need to comply with some new rule by an arbitrary date or my app will get delisted.
