Does someone know what needs to be done to be able to confirm ownership? I don't have this.txt file and I'm not sure what exactly it is and how to set it up.

Answer 1

Just click on confirm ownership button and it will take you to the next step. Even though it seems to be disabled it's still clickable

Answer 2

Follow the learn more link

First, you need to create an app-ads.txt file. It could only contains one line.

facebook.com, [your facebook app id], RESELLER, c3e20eee3f780d68

Second, put the file to the root of your website domain which was set in google play console. (for example, https://example.com/app-ads.txt )

Finally, click the Confirm button.

By the way, the learn more link says

Please ensure you wait 24 hours after updating the app-ads.txt before running authentication again.

but I confirm successfully in less than 30 minutes.

Answer 3

should my game be live before confirming ownership or i can confirm it even if my app is not live?
