Yith Subscription Billing Date Problem

Hello,

I hope someone can help me as soon as possible. so we have this subscription box to our website and set it’s billing date to every 28th of the month. however, our subscribers were billed on the 27th. we checked the date on the settings and it clearly says “Day 28”. Then why was our subscribers billed during the 27th? i hope someone can help me fix this. i checked the timezone of our customer and they are in the US. and the only time difference is 3 hours. but they were charged on April 27th at 1pm. we can understand if they were charged 3 hours earlier than us since we have 3 hour difference. but that’s not the case because they were charged in the afternoon of april 27th. how can i fix this?
