Amazon Photos App how to get subscription canceled immediately

I had Amazon Photo App on my iPhone with a 100 gig video storage subscription. I wanted to increase my subscription to the terabyte option. iPhone won't give me the option to change the subscription to a terabyte.

I chatted with Amazon. They told me to cancel the subscription on my iPhone and then uninstall the Amazon Photos app. I did both. I was hoping to go to the Amazon Photos site and change my video storage subscription to a higher level. Instead, the system kept referring me back to Apple.

The issue is that Apple still has it showing: "Your subscription is expiring soon. Your Amazon Photos: Photo & Video subscription expires on June 5"

I do not want to wait until June 5. How do I get this to cancel immediately?

Thank you!
