Can't create a new worksheet

Hello everyone! This afternoon I've faced the problem that I can't create a new worksheet. I'm in Ukraine and this platform was a great opportunity to conduct tests in a remote ways. I've sent a letter to support team. Here is their answer: Thank you for the email. LiveWorksheets will be out of the office in observance of Memorial Day as of 2:00 pm (Eastern Standard Time) on Friday May 27th & will reopen after Memorial Day on May 31st. Please note all replies are subject to delays as we will be unavailable due to the holiday. So I don't know what to do(((
