Trying to help my daughter with her subscription. She has a Plus subscription through google play. She wants to change that to an annual subscription through dropbox. Our best solution is to unsubscribe from google play and then resubscribe though dropbox, but when she tries to resubscribe though dropbox it still says that the subscription is through google play and she must handle it there. Is there a way around this that will enable her to not lose all her data? Thanks for any advice.
