问题
I created my Firebase app, created all the senderIDs & server key for Cloud Messaging. I tested and everything worked. That was last week.
This week I am doing more testing and getting an error returned to my php script: { ["error"]=> string(13) "NotRegistered" }
I log back in to Firebase, go to Project Settings -> Cloud Messaging and see BOTH the server key and the sender ID have changed. As well, the iOS linked app section just spins and spins and never loads that section. I haven't done anything. Is anyone else experiencing this? How can I get this fixed? I can't even see the full Server Key...and when I tried linking the new senderID back to my Play Store Developer App Console it errored out saying "invalid senderID". Thus I don't even think the new senderID and server keys will work...but at the same time, the ones I was using are not working now either.
