This is my pet peeve lately. I get e-mails from LinkedIn about my friend's new job or an article someone posted in a discussion group that looks interesting. I click the link in my Mail app, and it switches over to my browser, which takes me to a 20-second splash page, which then prompts me to type my e-mail address and password to log in, and then I'm asked if I want to "get the app," which I already have. Since the web app is terrible, I close my browser and then go open the native app and try to find the thing I clicked on in my e-mail, if I still care enough at that point.

They need to do something to fix this experience, which is quite broken.
