Adding a second win10 phone to my MS a/c devices

Hi, I added my Lumia 735 to my devices and it shows in the 'find my phone' in my MS a/c. But when I try to add a lumia 550 using the phone add a/c it does not show up when i log onto my ms a/c and look for it.
Went thru the 550 log onto the same ms a/c but nope its not listed anyone got any ideas?
