Needs a new update the photos and videos should look more clearer

I got charged for the pro version but I don't have it nor as can I find it.

This app rectified my TCL30v camera audio problem using short video mode. Regular video mode still causes audio distortion. Any guidance you can provide would be appreciated. I have tried every trouble shooting that I can think of but nothing works. Reaching out to TCL anyway but still keeping the pro app.
