"We singerly thank you for your warm welcome as we begin the US tour. As this is a chance to meet our fans who have waited patiently in the US, we originally planned promotions and a wide variety of opportunities for meet-n-greets. However, due to the severity of the COVID-19 situation, we have decided to had no option but to cancel all promotions, as the artists' health is our number one priority, and must proceed with the tour in the safest way possible.
JYP Entertainment and TWICE members are sorry and saddened to announce this. However, this decision is mandatory for a successful tour schedule, and we would like to ask for your kind and deepest understanding. To enjoy the concert full of joy in a safe way, we are very excited to perform for you, and sincerely hope that our fans will take care and stay healthy."
