Virginia) to an Amazon SNS topic in Asia Pacific (Hong Kong), change the principal in the queue policy to sns.ap-east-1.amazonaws.com. Opt-in regions include any regions launched after March 20, 2019, which includes Asia Pacific (Hong Kong), Asia Pacific (Jakarta), Middle East (Bahrain), Europe (Milan), and Africa (Cape Town).
