Student cannot join class even with valid email and proper link
I have a student who cannot join the class properly, even though she has a valid account. Moreover, it says that she is all alone and not in my class. I have still another student who is showing up as in my class but for her she says the message that she is all alone. There really should be an easier way, as for a teacher like me to add students and put in their information if the single method you offer fails to function.
The "you're alone" message is shown in regards to your students' friends list and has nothing to do with whether or not they are currently being monitored by you/a teacher. There are no overt messages on a student's homepage that indicates that they are being monitored.
If the student who is showing up in your class goes to their Progress Sharing settings ( https://www.duolingo.com/settings/observer ) your account/email and section/class name (if assigned) should display, confirming that she is indeed in your class.
If the student who isn't showing up checks the same settings it should be empty (or have a different "observer"/teacher if they have one). If this student fills in your account email address, and section/class name if applicable, they should be able to manually add themselves to your class.

Although I am not saying there couldn't be a better way, the current method (using the link, although there is also Google Classrooms -- but I don't know the ins and outs of that method) is pretty simple, straightforward, should work (given it's functioning as planned), it doesn't compromise the privacy of passwords, and it puts a nice check in place in regards to an account necessarily needing to give permission to be monitored. I can't just pick an account name off of the forums and make an automated attempt to imposition them with a request to track them.
I could see the potential in there being other ways for teachers to add students more directly, but anything I am imagining would also bring its own set of difficulties along with it. There was a post just made in the main forum about integrating with more third party application managers used in schools (similar to Google Classroom), maybe that's an option for the future.
