Recent problem. I'm on a call. I "Add Call" (3 way). The second person answers. I merge the calls. I can see both parties are there. The call is connected. However, the first person from the original call can't be heard. I can drop the second call and it goes back to the original call. The first caller still shows there, but I can't hear that person. They say on their end it seems like they've been put on hold and I never click back to connect. On my end it shows that it was connected though. This has not always been the case though. Maybe have started after an update. Unsure. It's been going on for a couple months I'm guessing.
