I have purchased prosp as deal is ending soon. Many users reported the bugs. I am also facing the same from start. Connecting linkedin profile took 2 hours at it was giving error for captcha. UI also have many bugs e.g. in campaign builder once you select leads and move to builder page you can not go back by clicking on leads tab. UI lags very much to load anything.
Still decided to use the prosp ai for 60 days under refund period and if the developer makes improvements then i am going to keep this product.
