Hello! It would be very useful to have a function to view your signature keys. I have a problem, I have uploaded an application to Google Play (using the online build of GDevelop). Now I want to update my app, but with a manual build. But I can’t do it because I don’t have my signing key.
We are unfortunately not able to share that keystore as you expect.
What you could do is request a reset of the signing key used. The steps are written here: How to reset the app signing key? - Google Play Developer Community
It takes a few days to be active, then you can try submitting a new package and see if it works.
