The APK is signed with a different certificate. Be sure to use the same keystore and key as used for

I keep getting this error when trying to upload my apk to applab, and i have already checked google and idk how to solve it. "The APK is signed with a different certificate. Be sure to use the same keystore and key as used for a previous version." Even though i have changed everything, i have looked through my keystores and there is only one that uses the key i have made.

Is this a Unity application? Can you make sure you aren't signing with the built-in debug cert?

Yes, I do use unity but i used a tutorial on how to build your game and submit it to applab and it worked

I looked through every keystore I had made before and none of them used the same key as the one i've used many times before

One message says you still have your key and the other says you don't. I'm confused 😞

If you don't have the same key as before then I think you'll need to re-publish to app lab as a different app. You need to make sure you keep your keystore in a safe and reliable place and you never lose it.

Wait, can you see the old keystores that you have used on old apks that have worked?

I just submitted a bug to meta through the dev hub, I'm going to try resigning the keystore to see if that will make it work
