Where are you getting this error exactly? in Android studio or in Coppercube editor? This seems to be related with Keystore or the signing certificate used by your app.

Please explain your error, what you are trying to do and where are you getting this error. make sure you are using the latest CC version and your build tools and platforms tools are of at least API 29.

When uploading to Google Play for testing this error appears. The CC version is the latest, and I have a purchased key. When trying to download the apk for the test in the Google Play Console, this error appears. All current APIs, including 29, are uploaded to the android studio sdk. Please help, because we want to make games on your engine, we have experience, but now it is impossible to put it on google play. Maybe we are doing something wrong?

Maybe these are the changes that google is introducing in August? We are very puzzled, because the content has been prepared, which was performed during the last six months, and it is impossible to post everything on Google play, we are puzzled((((

looking at the above error it seems you are posting the app for API Level lower than 20, which means in your android manifest you have mentioned min-sdk version lower thatn 20, you can try increasing min sdk version in your andoid manifest. Or it can be either bad keystore file, try creating a new keystore file and publish it again. If you are using android studio, try using release keys not a debug key certificate.

Reinstalling will not help. If you have Discord, then we can text there in real time and maybe I can help you there.
