I am very anxious to identify a vine growing in the ivy in my garden but I can’t get the app to work nor can I get a chat response from anyone. It is not poison ivy, not poison oak, and not Virginia Creeper. It has a single palmate leaf with five points that are all part of one leaf, not five separate petals joined on a single petiole. If I can’t get this to work, I want to cancel it immediately. I tried to do that yesterday and got nowhere. Very disappointed!!!
