Zoom is lifting the 40-minute time limit on Thanksgiving Zoom meetings so family members and friends can virtually spend the holiday together. Health officials advise people to not take part in large Thanksgiving family gatherings, especially with older family members. There is nothing you need to do to take advantage of this offer. Simply use Zoom as normal without the worry that your virtual Thanksgiving will be interrupted. The US Centers for Disease Control advises the safest way to celebrate Thanksgiving is to celebrate at home with the people you live with.
