I have mobile that is in production. I have deeplink
goflexieapp://goflexieapp.com/account_creation?referral=5680b85a-09f4-4444-a759-cc1993645375
or
goflexieapp://goflexieapp.com
both links work in apple devices. It opens app the apple store or directs users to the mobile app. But in android devices it either makes a phone call or it opens a web browser and it says the "goflexieapp.com's server IP address could not be found".
