We are submitting an android app to Amazon app store, it was rejected once because our app wasn’t using an secure connection for Sign-In/Sign-up requests.
Our concern is, if we use a self-signed certificate on server for HTTPS and use that server in our app, would that cause any issue with Amazon app store submission?
Would they require our SSL certificate to be signed by a valid CA?
Our app was successfully submitted with a few cycles of Bug resolving. Those were other issues not related to this.
My point is that you can use SSL with a self-signed certificate for submission on Amazon App store.
