I have hosted my AASA file in https://fast-prog.co/apple-app-site-association in signed format as per documentation.
I still can not see open in app button when open a link like https://fast-prog.co/swap/82 or https://www.fast-prog.co/swap/82in iphone.
By the way i have activated 'Associated Domains' and put proper entitlements as per documantation.
