I set up my pro board about a year ago. Used network cable. Worked great until I added my wife's cell phone. Now, whichever phone I use to arm, only that phone can disarm. Both phones display everything and get alerts, but only the arming phone can disarm. Did I make a log in mistake when I set up her phone? Both phones are Samsungs and I used the pre-installed app. I un-installed and re-installed apps in both phones, but still does this.
