Bug on Sound. Want my money back – Video Speed Editor - Slow and Fast motion effects for multiple parts of your videos Review

I paid for the paid version (so I could use a 8x speed) only to find out later that the sound has a bug. After I divided my video into 3 and changed the speed of the 2nd video to 8, and saved it on my phone, then played the downloaded video (because I there is no sound on the app itself) I heard 2 overlapping sounds playing together at the beginning of the video. I don’t know how long it went cause I didn’t listen to the whole video, but it was at least 30 seconds long. Rendered the video useless. Waste of time.
