I’ve just tried typing in that URL www.facebook.com/device into a web browser on both my iPhone (iOS 11.0.3 & Safari) and my PC Windows 7 & IE11) both display a page where the “Roon” code could be entered.
Just wondering if you typed it into Facebook app rather than a browser.
Thanks for touching base and sharing your feedback with us @Chrislayeruk, the insight is always appreciated!
I touched base with our techs yesterday to get an idea as to “where” the team is in addressing this behavior and per the conversation, we are planning on addressing this before our next feature release.
I took a look at our ticketing system today and I can see that work for the “fix” is still in our development queue which means that the DEV team is still considering when this work should take place. Once the team has scheduled this work and it moves up in priority I will have a better sense of when a fix should be expected.
