Removed time limits for schools affected by the covid-19 pandemic

I've seen some accounts with the school ending code receiving a notification that after July 1, 2022, the time limit removal will no longer be supported.
I am a user in Vietnam, some of our provinces are still affected by Covid-19 and continue to study online. I have and a few friends who have been helped by the school to set up a Zoom account that is supported to remove the time limit with the extension code @hanoiedu.vn. I used this account but did not receive any notification that after July 1, it will no longer be supported to remove the limit
Can the Zoom team help with more details about this and if my account code is still supported. Thank you
