I've been using this app for a couple of months and I want to say it's not like tracking packages. It's regular mail so it's not really "tracking". It's more useful to see how many mails coming to you but it cannot accurately tell you when they will be delivered. Also, the app only highlights ad mail from companies and most other "useful" mail will fall into general mail category without showing a sender. I don't think it's what you think it is.Found this app from Canada post which seemingly tracks mails directed to your address (my mail feature) - https://www.canadapost-postescanada.ca/cpc/en/support/kb/other-products-services/using-tools/mobile-app
Has anybody tried this and was successful in tracking PR card delivery ? if yes this could prove to be helpful
