Hello @rew_data,
You might want to check if you region is available to use Databricks Apps, please refer to: https://learn.microsoft.com/en-us/azure/databricks/dev-tools/databricks-apps/
The error message "This workspace has a data plane configuration that is not yet supported" could occur when the workspace's data plane region is not the same as the control plane region. This configuration is currently not supported by Databricks Apps.
You should check if the data plane region of your workspace matches the control plane region. If they do not match, this is likely the cause of the error.
