Who is running a success Mobile App without using Google/Apple app store and how are you doing?
I would like to know how we can deliver our apps in the future, without going through a detached gatekeeper; whom believes that having a canned-bot reply to your problem, constitutes as 'Good service'.
Backstory: We run a SaaS business telco which focusses on privacy. Needless to say, our mobile app is important to our customers. We are currently experiencing a problem publishing new app versions to Google Play, our app is being flagged as “uploading user’s contact data without consent”. We obviously aren’t doing this, but we also don’t know why Google thinks that we are and it’s not possible to speak to a real person, you only get automated responses when you try and appeal it.

For Android, you can offer direct apk downloads, but you also should try to stay in play. Depending on your market, some % of users will be willing to do a direct download, but likely a majority won't.
Also, Google has 'Play Protect' which will prompt users to remove apps they flag as malware --- if their store review process doesn't like your app, Play Protect might not either.
