Globo Product Options, Variant

if you are existing Free user of Globo Product Option, Do not ever try the trial, it does not allow you to switch back to the "Free Version" if you cancel the trial and are forced to pay the subscription fee. The only advise i was given is to uninstall the app and reinstall back but all my options will be removed and refund in App credits. and the new 'free version' does not come with the features which I am having previously.
