I have tried looking for a couple of friends and it won't find them it does nothing.
I have been told the servers for the Android Databases are separate servers from the main Striiv servers so you can not at this time add friends using the other version.
I was able to find and sent you a friend request Stefeni.
I obrien, I found one person searching for obrien but I'm not sure the name was a match. Feel free to look me up by name and request me. I'm mostly using the old iOS app but I still carry my phone with the other.
