Hey all-
Harmony updated its iOS App today (to version 4.0.6). I have version 4.2.48 of the Harmony Hub firmware.
Everything works perfectly – almost (for some reason, IFTTT tells me that there are errors running the recipes even though the recipes get executed).
I created virtual on/off button tiles for all of my Harmony activities - using IFTTT, the Harmony activities get turned on whenever the corresponding switch is turned on.
Best thing is now when I turn on my Sonos, the receiver automatically sets to that input. Yay!
Hopefully the update solves your issues as well.
