Hi Thunkable Community… How to change SHA codes of the project. I had published an app in August 2020 and accidentally deleted the project on the thunkable platform. When I upload my app on the app store it says SHA fingerprints don’t match. This worries me because my userbase isn’t growing. Since then I tried changing SHA but couldn’t. Thankyou ---

Have you been using appinventor or kodular to publish your app before @joel ---

If you were using them you need to export keystore from that builder and then import it in the project settings of your app. 😃 ---
