Yes, it's fine. Please report it if it's not accepted.
Perhaps this isn't the best place for this question, but I just thought of it because I clicked 'conjugate' on the verb 'gehen'. Can anyone explain to me why DuoLingo indicates that 'gehn' is an alternate accepted conjugation of (wir/sie/Sie) 'gehen'? I looked up the conjugation of the verb elsewhere on the internet and didn't see this alternate version. Is it colloquial? In a first year German university class, would these alternate conjugations likely be considered acceptable on an exam? (In my experience with other foreign language classes, professors don't tend to accept colloquialisms on grammar tests.)
