My requirement is to create simple Facebook app linking to open installed app / redirect to app store link. I have followed instructions on below link https://developers.facebook.com/docs/app-ads/deep-linking
I am able to create link immediately but problem is when I click on created custom URL, it is always redirecting to App Store link and not opening already installed app on the device. Strange thing is in browser if I provide "mytravelapp://" (one of field in above instructions on Facebook developer account) it's opening installed app. But do not know why on created app link URL, installed app is not getting launched and always redirecting to App Store link.
Any help would be appreciated, though it looks quite simple.
