Can I use WeChat Pay to pay for retainers after hours or on weekends?

WeChat Pay is an online payment platform, which means that it can be used to make payments 24/7, including after hours and on weekends, as long as the service provider's payment system is also online and accessible. However, the availability of customer support or the ability to resolve payment issues may be limited during non-business hours. It's best to check with the service provider directly to understand their payment policies and customer support availability during non-business hours.
