Thanks for the feedback @IanTerry - we expect the tool to work identically between the app and the webpage. What differences do you see?
When things don't work on a cloud managed product, it almost always means you'll have to be on-site to do any troubleshooting. The only remote diagnostic that can truly be made is denoting the hardware as online and configurable, or offline and requiring some troubleshooting.
A new tool was introduced about a year or so that creates a quick-link to the local status page of the hardware if you are directly connected to it. We should do more to draw attention to this link, as the local status page typically has relevant real-time information about problems with the device.
What is a problem you faced that would have been solved with a missing tool? We can work on getting it in the app for you!
