Does anyone know why I am always getting this error in the backoffice log viewer ? how can I fix this ? System.Security.Cryptography.CryptographicException: The key {a773867b-d0d3-4648-8378-2042cd1895c7} was not found in the key ring. For more information go to http://aka.ms/dataprotectionwarning at Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingBasedDataProtector.UnprotectCore(Byte[] protectedData, Boolean allowOperationsOnRevokedKeys, UnprotectStatus& status) at Microsoft.AspNetCore.DataProtection.KeyManagement.KeyRingBasedDataProtector.Unprotect(Byte[] protectedData) at Microsoft.AspNetCore.Session.CookieProtection.Unprotect(IDataProtector protector, String protectedText, ILogger logger)

Bit late in reply maybe, but does this appear after an app recycle, or an redeploy on Azure ?
