I have never subscribed to the premium free trial on any app, it wouldn't be different for this one. I created an account and didn't use Jira at all after that. I checked the emails and it said that it would downgrade to free if payment methods werent inserted.

It didn't downgrade at all! In fact, i even got a bill somehow

I tried cancelling the subscription, even if a day has passed after the expiration date, but it got scheduled to next month! I don't know if thats how it is or not.
Im genuinely confused. Can someone help me please?
