I want my app to open when I use my desired URL. In the FF tutorials, it says to use any domain as long as it doesn't conflict with any other app on the user's phone. But I am not able to use "https." Is there any reason why?
Also, assuming I need to buy my custom domain, does it have to be a ".com"? Or would any other suffice?
Also, as Firebase Dynamic Links wont be there for long, what is the alternative?
