I can’t send invitations to people I know that are interested in LingQ. After entering the email address and clicking on “sending”, it is indeed notified to me that the invitation have been sent but those invitations are not written on my tab. I sent some at the end of November and everything worked well. It’s no longer the case.
It might be useful to know if some of you encounter that issue. Make a test, and tell what happens. Thanks.
