Conference (3-way) Call Not Working in iOS 13
I just realized that (3-way) Conference Calls don't work with the latest iOS 13.1.2 and iPhone 11 Pro Max. I'm on AT&T and have used this feature frequently and without issue in the past. However, I realize that when I try to add and merge calls the feature does not work. It hangs and the 3rd person isn't able to join the call. I can connect to the individuals holding on the lines, but can't merge them. I'm wondering if this is a known issue or just a random bug. This is a basic, but critical feature.
