Expo app signed error, i cant push new version.

Hello, I’ve installed the app to google play store. However, when I wanted to open a new version again, I got an application signing error.

I’ve increased the Version code once.
But it didn’t work. Application signing error has exhausted me.

Please help me. I’ve tried many times.

I’m not entirely sure, but maybe check the format of your keystore:

How do I check the format.

As per the post:

keytool -list -keystore [keystore_name]

I’ve been trying for a month. Please help me.
