I created a direct publisher channel , and in the monetization page, when you select 'yes' it's asking to enter the URL where the app-ads.txt is hosted.
I have tried to google search everywhere, but cannot find a solution? Has anyone encountered this and would know how to host an app-ads.txt file? There are lots of sites that can host it for you but they are mostly mobile apps ( android or iOS) specific and ask you to enter the URL of the app.
Please help us out, I have exhausted my search, and this looks like my last resort.
