I purchased recently a Huawei P20 lite phone. I have been in the process of installing my favourite apps. All have loaded successfully except Amazon Music for which I have a subscription. Every time I try to install it I get "Error code: -505" message. I have searched the web for solutions, none of which have worked including flushing out the cache and data for the Play Store, disabling/re-enabling it and, of course, switching the phone off and on.
Thank you FE, but no joy. I did not have Audible installed. I downloaded it and made sure it was enabled, but I still get the same error message. My annual subscription runs out in early June and I was planning to go back to Spotify anyway. More expensive, but superior.
