New to Audi with ‘19 Etron; coming from Tesla.

Hello. There is such a learning curve with the electronics. I have so much to work through. We’ve followed the instructions for regenerative breaking. Does this feature have to be adjusted every time you drive? It’s not as strong as the Tesla was. I love the car but need to find a user group to learn how to use the car. The manual is very hard to follow!
Thank you in advance for your help.
