Thunkable to Android Studio and update app

He wanted to know if the following happened to any of them:

When I want to upload it I added thunkable’s android.keystore certificate, but when I try to upload it says:
You have uploaded an APK that is not signed with the upload certificate. You must use the same certificate. The upload certificate has the following fingerprint:
Do you have any idea if something can be done? or do I have to upload it back as if it were a new app?

Hey @matias.panusopuloszh - were you using Thunkable Classic?
