Azure App Service
Azure App Service is a service used to create and deploy scalable, mission-critical web apps.
I already saw that.
That does not apply to the Azure Portal.
Cannot update an environment variable under web app/settings

This is a production system and I have never seen this error before. It started about 30 mins ago.
There are no other people changing settings, there is nothing but me changing one variable.
When saving the environment variables screen after making a change to one variable I get the error:
Updating app settings
Failed to update app settings: There was a concurrency conflict. Configuration update for Microsoft.Web.Hosting.Administration.WebCloudProvider failed for maximum number of attempts UpdateSingleSiteConfigurationWithRetry. Failure details: navster
This is a very high priority issue.

This issue appears to be corrected as I can change environment variables in the Azure Portal as normal now. Thanks for your response and support.

Thanks Paul Upson for sharing, Using the
Azure.ResourceManagerNuget package to make these web app settings changes in an custom automated deployment application.scenarios in which we were experiencing this response, we were not using a retry policy with the ArmClient. We haven't experienced this response when updating web app configuration with a suitable retry policy in place.
