Phone Won't update config file
System is 125 devices. Ver 12.4 from 12.01-12.02 Short is Customers iphone won't take the latest config file. Both my phone will. Long is. This was a add on to a system I built a few years back. Was originally a one main system. Had to move and reactivate some existing to new repeater. Before I went to demo system to owner I tested on my phones and local control. All Was good. Pulled out his phone and lights started reacting slowly. I though maybe bad transfer. So booted back up and retrans and tested on my phones and all was good. Took a few back and forth and bad words(in my head) before I realized his phone wasn't updating. Went into diagnostics and tried to re-download and it wouldn't. Turned off WIFI and used Cellular. Didn't work. Turned of Cell and tried WIFI. Didn't work. Turned off Cell Data in the APP. Didn't work. His phone would get system all confused. Give it a minute and all would sync back up. My phones still all good after a few minutes. Not being a Iphone person I wasn't sure how to delete and reinstall. Either was he. Odd thing was I went through his many many many pages of apps and folders and couldn't find the the app. only way to run it was to search then open from that menu or from the app store. I did have to find the connect again. When I added the second main it said network setting have changed and you need to reactivate the connect bridge. His app vers is 7.4.5
