So if I do mobile check in, LH would not credit the miles to my account, same with OLCI or kiosk check in (and I do not see an option to add a FFP number at check in with those three instruments) The only way I can do this is if I actually talk to a real person at bag drop off.

Very annoying and outdated selection of features. Other airlines are really way ahead when it comes to that!
