Has anyone used this app to ‘copy’ politicians trades? Does it work well? Insight appreciated.

Hey everyone! I just joined the group because I have a special interest in the ‘dub’ app. The adds I see say that you can copy certain individuals and politicians stock trades. I have an interest in stocks but work 80-100 hours per week so it’s hard to stay on top of it. I am wondering if anyone has used the app? What did you like about it? What did you dislike about it? Do you still use it? Would you recommend it to people? Thanks!!!!!!!!!
