confusing “Upload failed” message in Google Play C

问题:

I would like to add a new App to Google Play. I have already some apps signed and published to google play. All with the same key. Now with the new one I get the message :

 Upload failed

You uploaded an APK that is signed with a key that is also used to sign APKs that are delivered to users. Because you are enrolled in App Signing, you should sign your APK with a new key before you upload it.

In the console it looks like the following :

I am not sure if it has something to do with "Google Play App Signing" ?

Can someone help ?

In the step of creating the first release, there was an button called "Reuse signing key". Is that what I should have clicked, if I want to sign the app like my older ones ?

In Google Play App signing Google Play signs the app for you. You should upload signed with a new key, called the upload key.

If you really want it signed with the same key as your other apps (I wouldn't recommend this) then you should opt-out of Google Play app signing for this app.
