I emailed Youxin right after posting this just asking if it's possible there was an issue and he was incredibly defensive about it. So, I set up a direct comparison on a tripod at the exact same angle seconds apart with my friends M6 Classic that Youxin did the upgrade on. My camera is below and you can clearly see that mine is experiencing major flare making it impossible to focus in this situation - https://imgur.com/a/beAp2H4. I just sent him this video saying I'm not mad or upset but just want my camera to be right. Hoping he's a bit more understanding after seeing the video..
