I had exactly the same experience. It seems that the previous update to the Phone Link app has created this situation. I've raised a support call and had a technician research the problem. Apparently, it is a problem within the app and there is no official fix available. I had hoped the latest update would have addressed the issue, but it hasn't changed a thing!
Glorified phone dialer is far too succinct for me! Rubbish, is what I would call it!
