I've purchased the Raid pass before in the past (3 times) and have cancelled it each time after purchase to avoid the payment renewal (I end up buying it again like a month or 2 down the line when i feel i need the extra Multi-Battles). I've now bumped into the issue of not being able to purchase the Battle pass at all. I thought this was an issue on the Google Play side, but I've been working extensively with their customer support and we were unable to find any issues or settings that would hinder the Raid Pass purchases. 

Google Play CS then recommended to seek help from you guys. Is there anyway you guys can fix this on your end?

Thank you for your time.
