1. Go to https://app.powerbi.com/groups/instance_id/gateways
  2. Under the "On-premises data gateways" tab
  3. Add back the indicator that shows whether there's a gateway application update available with a hyperlink to download the latest version. This used to exist, but was removed. I relied on this heavily.. The user experience is now greatly diminished. It takes 10x longer to figure out whether the version I'm running is outdated or not.

As an added benefit, it would also be great if you could send an email notification when a newer gateway version is available vs the one you're currently running.
