I'm using a iPhone to monitor PRTG but I only see errors when opening the app. We have all our systems (and PRTG server) in a private network without internet connection. On my phone I have a private APN so direct connection to the network.
I know that in order to use Push notifications the PRTG server needs to have internet acces, but on android phones of my coleages the notifications get fetched every 15 min. Whatever I try, I can't get this to work on iOS.
