I'm using the new Google Play console version and I'm not able to find how to load a mapping file in case of obfuscated APK. I looked at every menu, I looked at the docs, can someone explain how to load the file with the new interface?
Solution
Click on "Releases Overview" in the left panel.
In the "Latest Releases" section, click on the version for which you want to upload your mapping file
In the "App Bundles and APKs" section, you would see a row with your added App Bundle or APK.
Click on the 3 dots menu on it's right end. This would open a menu with an option to "Upload ReTrace mapping file (.txt or .map)"
