Answer 1

How can facebook crawl the app-ads.txt file from the domain?

See the app-ads.txt specifications here: https://iabtechlab.com/wp-content/uploads/2019/03/app-ads.txt-v1.0-final-.pdf

which says:

Provide developer website URL in app store listings

This specification relies on the presence of a developer website URL within the app's store listing metadata in all app stores distributing the app. Many app stores currently collect the developer's website URL to display as developer contact information within the store. Publishing a website and providing its URL is required for the app's ad inventory to participate in the authorized seller scheme. Using this website URL, interested crawlers will derive a path and attempt to crawl an app- ads.txt file on the corresponding domain.
