Worst timing ever, tried to add ERA 300s as rear surrounds to a ARC and 2 Gen 3 subs, removed my 1 SLs, system won’t recognize them. I have family  arriving for week and my system is all jacked up. I reset the ARC, 2 subs, 4 1Sls and the 2 era 300s, added them with great difficulty, but they want a update then say they can’t connect to my WIFI even when they are next to router. Will the S1 app work? I found it on google play for android.
