Getting "page unresponsive" error continuously

After login to cumulocity page, getting error as “page unresponsive” and taking more time to navigate through pages. Here I am attaching a screenshot as well.

That’s quite a lot of measurements in one graph :wink:
The Measurements tab in Device Management tries to visualize all of them unfiltered which is in your case too much data to handle and not readable at all.
Workaround: Use the Cockpit + Dashboard and select all the data points which are relevant for you only (not all of them).
