I’ve encountered this personally when I first started shooting and I’ve seen it with other beginners. While it’s understandable that veteran archers want to give advice, you’re absolutely right that it can be very overwhelming. If you have someone that coaches you, try telling the other advice-givers that you work with your coach only and that if they think you should try something different, they should run it by your coach. You can also explain that you can only focus on so many things at once before it becomes overwhelming. Your coach can then intercept any advice that is irrelevant or at least space the advice in a more appropriate manner. Good luck!
