We are working on this, but so far we haven’t been able to reproduce the issue.
Have you tried changing the graph monitoring values? In your screenshot, they are set to Solar Power and Solar Current. Could you try switching them to something else and then back to Power/Current? Does it make any difference, or does the graph continue to show an empty state?
Thank you for the reply @jperez. I tried different settings to display and the graph remains at the same empty state. I tried un-installing the app multiple times between my devices and the issue remains.
