Video blown out/Subtitles don’t match – Video Teleprompter Lite Review

I’m a paying customer and despite repeated attempts to reach customer I get zero response. The subtitles start too soon and don’t come close to keeping pace with my words no matter how I adjust. It won’t let me “lock” a size font and speed even though I use it everyday I have to reset it everytime. And the app blows out the video when I hit record (yes after setting the aperture and locking it.) They offer a customer service email, but don’t respond. So I’m trying publicly. To the app developers or anyone who cares: Please respond with information on how I can connect with a specialist to troubleshoot or suggest fixes. Thanks!
