Cluster state stuck on 'Updating'

I’m running Rancher 2.6.5 and I have a cluster provisioned to AKS.
I did upgrade this cluster from Kubernetes 1.20.9 to 1.22.15. Unfortunately the update on Azure has been blocked due to a Network-Policy. After removing the network-Policy the update finished on AKS, but the cluster state on Rancher is still stuck on ‘This cluster is currently Updating’.
Everything works fine, but I have no clue how to tell Rancher that this cluster has succesfully been updated.
Anybody has an idea?
Many thanks!

The same behavior here…
Did you solve??
