Invalid Dynamic Link when testing manually created link

[timfong888]

I cannot seem to get my dynamic link to work. It comes up as invalid. When I debug with d=1, the error I get is that the domains for deep link and dynamic link need to be different, but I don't get that from the documentation.

This is what I have used:
