I'm having issues with a custom built js player that runs google ima ad tags and a live video stream.

Hi. I'm having issues with a custom built js player that runs google ima ad tags and a live video stream. I had the player built, but the bugs keep coming and the person who built this, takes 2 weeks and charges me for bug fixes (3 times now) even though , it should have been perfect the first time. So I've already spent too much on this project. Hoping for a quick/easy fix that doesn't' cost much. More work is guaranteed. Here you can view an example of a live vid js player: [login to view URL] The issues with this particular player: #1 On iphone 7 and iphone SE I saw the ad overlaps over and over again and doesn't let the stream play. #2 The last freelancer created an on-error message, if the stream is off/down. This only successfully works via edge player. No other browsers show it. I need it to work on all browsers. Also, I noticed, when It does work, a full video ad plays first. Please allow on error to display if cam is down with no video advertisment/preroll. #3 Microsoft Edge has issues playing back live stream. It successfully spins ad, then plays live cam, but freezes after 8 seconds. I need this fixed/streaming perfectly. Thanks!
