Android Question Unsigned releases from Google Play Google doesn't protect your app's signing key. Sign up for the program to use the Android App Bundle.

Hi Guys,

I'm updating an app that I haven't updated since 2020; when I create a new Play Console release it tells me:

"Unsigned releases from Google Play
Google doesn't protect your app's signing key. Sign up for the program to use the Android App Bundle."

Can you help me take the right steps to be able to publish the update? What should I choose, I did not understand the next steps when I press the activate key.

Can you help me???
