I'm having a problem setting up a deployment source on an Azure Web App.
Continuous deployment had been setup and was working fine for me before, but currently I can't set up a new deployment any more.
When I attempt to set the Deployment Source for my Web App in the portal: Deployment Center -> Azure Repos -> App Service build service -> choosing my Azure DevOps repo -> Continue -> Finish, it fails with the following error:
Repository 'UpdateSiteSourceControl' operation failed with Microsoft.Web.Hosting.WebHostingException: AADSTS700027: Client assertion contains an invalid signature. [Reason - The key was not found., Thumbprint of key used by client: '############################################']

I tried deleting and recreating the Web App service, but that made no difference.
