Google took 5 days to reject my app because I didn't include a privacy policy on the store's listing page. And it's unclear where I'm supposed to add it. Just like… in the description?
There's this support page https://support.google.com/googleplay/android-developer/answer/9815348?hl=en
Which says it should be in the Play Console, then under "Store presence > App content". But there is no "App content" menu item.
Cool stuff. 🙃
