  I haven;t used Airbop inn a while to send messages but have always been able to with no problem. However, I now receive this message. Error 401: GCM authentication error

 Can you tell me what I need to do to correct it?

Thanks in advance!

    Hi Linda,

    If you're still using the Google Cloud Console and you haven't sent a message to the app for quite some time, it could be because you previously created an Android key instead of a Browser key in your Google console. If you are not using a Browser key, use the following instructions for creating one:

    Make sure you are generating a 'Browser Key', not a 'Server Key' or an 'Android Key'. Also make certain that there is nothing entered in the "Allowed Referrers (web sites)" box.

    If you are currently using a Browser key, you'll want to "regenerate" the key.

    Once you've regenerated your key, update it in AirBop and try again.

    If you've checked the above settings and regenerating your key didn't work, I'd suggest trying the Firebase console instead using the following instructions:
