Remove time limit

Hello Zoom team, I am a teacher working in Vietnam, recently I and my colleagues were provided with an account under the educational system with domain names @moet.edu, @hanoiedu..v ..v this account is supported to remove the 40' time limit for online teaching due to the Covid-19 situation. But on October 8, all those accounts were no longer supported with the unbound feature, although the Covid-19 situation in Vietnam is still very complicated, we still have to explain. teach online. Hope the Zoom team can help us. Thanks very much
