Neither can I - never have been able to do either except when I used to travel with CO.

I enter my passport information (I'm BRITISH ) and country of residence (US) but it keeps saying "you can't check in online and have to check in at the airport".

CO used to have this - Obviously, Delta's website is lacking this module.

I can't believe I'm the only one in this situation. You are not - so are me, my wife and daughter

Does anyone have similar experience? See above - YES

Maybe we could team up and put pressure Delta to fix this problem.good luck
