I had RC surgery in Dec. 2019. The surgeon described the injury as "severe and irreparable", however the surgery was successful. Prior to the fix I could draw my bow, with some pain. After surgery (Sept. 2020) I could easily draw, but thet biggest problem I found is how weak I had become. The doctor emphasized avoiding any movement that could reinjure the shoulder, so other than PT, I didn't push it. As a result my overall physical condition declined and I'm still working to get back what I lost. My advice is to do the shoulder PT and add exercise that will maintain all other muscle groups during recovery.
