FedEx Dilivery Manager does not work. I have reported this issue since 2021. I installed to provide instructions to hold my package, and/or use functions of delivery manager. I have spent many hours with many agents reporting the issue. Each time it ends with a tech agent saying "we are aware of the issue. Don't use our app, use the web page". What kind of company knowingly does not fix glitches in their app for over a year? Do they regard credit card info the same way? Not recommended!
