Changes to the display of charts on Cayenne Mydevices' IoT website and app on the Wemos D1 mini

Hello,
some time ago (2016) I built myself a small circuit on a Wemos D1 mini co-working with the IoT site Cayenne mydevices.

The website and app had 'cool' charts of 1 day, week, month and year that you could zoom in on and now you only see the current data.

Has anything changed? Do you have to pay?

I don't see any information anywhere...
