Revert from trial Premium to classic view

[SunsetRunner]

I signed up for a three-month free trial period of Premium. After a few days I have decided to cancel it as the additional features are not of benefit or interest to me and, more important, the changes to the interface (e.g. when you drill down to get sleep information for a particular day) actually make the Fitbit iOS app less useful to me not more.

Unfortunately the cancellation doesn't take effect until the end of the trial period in June and I don't want to have to put up with the inconvenient Premium interface for another three months.

My question: How do I get the app to revert to the classic/non-Premium interface now?
Is there some setting I can change?
Or can I arrange to have the trial period deactivated by a Fitbit staff member behind the scenes?
