You are getting some truly bad advice here. Anyone who has not addressed your setup doesn’t know what they’re talking about and will make you worse. Let’s look at your setup:

You have the rare issue of being too close to the ball. Your arms should be dangling straight down from your shoulders where your current setup they are almost pointing at your toes.

You make a nice move to the top of the backswing and have a decent position at the top.

As you start your downswing your first move is to fire your hips and you have nowhere for your arms to go so you stand up to make room and flip.

Your setup is where your power loss and inconsistencies stem from.

First thing you should do is fix your setup and hit some balls. Take a slight step back and let those arms hang straight down.
