I used to have a X20 as my main deco for the mesh network.  I loved the internal speed test from my modem to my Deco i was able to keep the internet provider honest.   Unfortunately when i upgraded to the XE75 Pro the internal speed test was not available in the app.  I have called TP link and requested they bring it back. They said if they get enough request the would.  The speedtest.app is not the same.  Please bring back the internal speed test in the app.
