Phone app shows me as offline when the app is not in use. I don't get incoming calls because it shows me as offline.

Incoming calls don't come through to my phone. I use the desktop app to send texts. I use the phone app to answer incoming calls. I'm unable to change that offline setting from my end. I have to get with customer support for assistance and the wait time is awful - agents unavailable when calling the number; currently have been waiting 45 minutes through the live chat. No one has time to do this.
