We have two different servers that send out alerts. One is a "Push" server and the other is the "Current Events" server.
The "Push" server pushes the alerts to you when the app is in the background and a new alert omes through.
The "Current Events" server checks when you launch, update, or change locations to see if there are any current alerts for the location.
We experienced issues with the "Current Events" server, which is what causes the "ErrorUpdating Alerts" error and that should be patched at this time.
We know that this is a nuisance, but you will still receive push alerts to warn you of impending severe weather, and this error message does not mean that your weather data is not updating. We are upgrading our infrastructure to prevent this error in the future.
