Conference call with more than 3 participants?
I read that you can have a conference call with up to 5 participants on your iPhone. I have an iPhone 6 running iOS 12.4.5. I tried to have a conference call and followed the instructions. It worked with the first two callers (Tap "add call" then "merge call") but once I had the first two on the line, it would not give me a "Add call" option. I tried it again thinking I should add all three callers before I hit "merge call" but it wouldn't allow me to do that either. What am I doing wrong?
