Some minor issues I've been using this app for years. However  when trying to only backup a specific group  such as """"""""""""""""starred in android"""""""""""""""" it will only back up my sent messages and not those of the sender. The only way to get both halves of the conversation is to back up form """"""""""""""""everybody"""""""""""""""" then I have to go in to gmail and delete those I don't want. It IS the only app I have found that accurately backs up in Gmail in a format that is readable.""
