AWS Managed Grafana enterprise plugins not working

We have been successfully using the Snowflake enterprise plugin in AWS managed Grafana for several months now. It started failing all of a sudden and all our dashboards are unable to access data from the source. There were no configuration changes on our end.

We are unable to configure any new data source with any enterprise plugin and we’ve already been charged by AWS for enterprise in November.

We’re seeking help from AWS technical support as well, but has anyone had a similar experience in AWS managed grafana?
