Am I supposed to generate a new Keystore for every app? Or am I supposed to have only one Keystore and put it in every app I create?
thanks for any help
You can do it either way

thank you for your suggestion
Its better to create a single keystore for all your apps as it is easy to manage. You can backup your keystore in a safe place and never lose it. If you lose your keystore you will not be able to update your apps.
If you lose your keystore you will not be able to update your apps
You can "restore" it if you opted-in for Google's "Play App Signing"
If my memory serves me correctly. According to the instructions on Google's backend for uploading new apps. They recommend using the same keystore for every app. It had me sign up for the Play App Signing, as Simple Games mentioned as well.
