Madonna is delaying her highly anticipated Madame X tour, due to issues with “highly specialized production elements,” a Live Nation promoter told Variety in a statement.

The tour, originally slated to begin Sept. 12, will kick off five days later on Sept. 17 at the BAM Howard Gilman Opera House in Brooklyn, New York. The Sept. 12 and 14 shows at the venue have been rescheduled to October 10 and 12, respectively, with tickets being honored at the new dates. The Sept. 15 concert, however, has been cancelled and fans will receive refunds automatically.

Though Madonna has not commented specifically about the news, she did take to Instagram to post a statement. “Madame X is a perfectionist and her fans deserve nothing but the best!!” she wrote, before adding: “Thank you for your patience.”
