I am trying to submit an app with a split binary via Unity 4. I am using the 'split binary' option, producing a small APK with an .obb extension, everything builds fine, but google play keeps kicking out the same error when I try to upload the APK: "Google Play requires that the certificate used to sign the apk be valid until at least October 22, 2033. Create a new certificate." I am using the default 50 years for the certificate, have double checked passwords, and have re-traced my steps and re-created a new keystore. I do not know what is causing this. I am using a US calendar, Central time zone. Does anyone have any idea what is causing this?
