Canceling – Any.do: To do list & Planner Review

I am upset because I purchased the premium to connect to a friend and son regarding tasks. The app will not allow me to invite anyone? I had no problems when I purchase the app in the past. I let go of my subscription because I didn’t need to connect with others, but I do now. If this can’t be fixed, i would like a refund.
