Dynamics 365 integrations failing

Dynamics 365 integrations failing

Some of our Dynamics 365 integrations failed overnight reporting error:
Refresh the access token: {"error":"invalid_client","error_description":"AADSTS7000222: The provided client secret keys for app '6120e4ad-833a-48c0-a0dc-5463afd9dd70' are expired.

I tested the connection and also tried to "Sign in with Dynamics CRM" - but the above error immediately appears before even getting to the login page.  I've also tried other Dynamics connections to different environments, but these are also failing the same way with the same error.  I've checked out Azure portal and can find no trace of the App with the GUID in the error.

I suspect that the failures aren't to do with our environment, but with Skyvia's Azure environment.
