I am an account holder for my Team ID. I have paid Apple Developer Program too! Unfortunately, I see "Join the Apple Developer Program" and getting "Your Apple Account is already associated with the Account Holder of a membership." message. Also, I am getting "Unable to find a team with the given Team ID to which you belong. Please contact Apple Developer Program Support. https://developer.apple.com/support" error when I go to Certificates, IDs & Profiles. Help!!! Give me fix!!

I keep getting "Invalid Toolchain. Your app was built with an unsupported SDK or version of Xcode. If you plan to submit this build to the App Store, make sure you are using the versions listed in https://help.apple.com/xcode/mac/current/#/devf16aefe3b or later. (ID: db8516fc-1577-4462-a983-bf8c57483cec)" when I am attempting to upload a update that adding support for iOS 17 and iPadOS 17 of my app to App Store Connect! I am on Xcode 15 RC which was released on September 12, 2023. Anyone can fix this error?

After my app was approved on App Store, I haven't seen the app on my Apple ID's App Store purchases. It's the same Apple ID I used to submit my app to App Store. My app's name is Archer Gift Stickers. The same app cost $3 I chose the price. What I should do?
