Looking at all of the set up and help guides it states from the app I should be able to select a unit and see details such as signal strength.  I am only able to see the MAC address, IP address and that the "Deco is working well".  I am missing signal strength and the upload and download speed, according to the documentation.  This thread appears to have had the same issue, https://community.tp-link.com/en/home/forum/topic/221660.  From the responses it seems it was resolved, but the solution is not inline with the thread.

Any ideas?
