Intercom not working correctly

I have been trying for the past few days to get intercom to work but I have been having issues where after checking all setting are in place, phones are up to date and notifications are on, my family does not receive the notification of an intercom. I also experience the issue when I try to make an announcement my phone tells me I need to turn it on from the home app even after I turn the feature on, has anyone else had this problem and found a solution?
