Is it possible to revert to the classic view on app after cancelling Premium?

[Thom_C]

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?

@Thom_C It's nice to see you on the Community. Sorry for the delayed reply. 

Thanks for letting me know that you've signed up for Premium but decided to cancel your subscription. It's not possible to revert to the classic view of the Fitbit app because your subscription will be cancelled until June. 

In the meantime, you may want to check your sleep information on the online Dashboard instead of the Fitbit app to get the classic view that you had before. 

Thanks for your understanding. I'll be around if you have any additional questions.
