Issues with creating Release package


trying to create a android release package and when I add Android credentials they don’t save, still has ‘Add Android’.

And when I press ‘Package Project’ it comes up with ‘there was an error with your build’

I’m using a keystore file/password & alias/password supplied by the programmer who created the previous version in ionic CLI.

Tried using the help chat in ionic creator but that was 6 days ago and had no reply.

When I add iOS credentials it then shows ‘Replace iOS’ and when I press package project it shows the notification ‘package will be emailed to you…’ so I’m getting further
(getting an error about No code signing identities found but I look into that later).
