There’s been a problem with a previous purchase
I keep getting this pop up when trying to both install and update apps that have no cost at all. I did purchase a subscription in the past but cancelled it as it was no use to me. And yes I cancelled it before the due date (was a yearly subscription). Im not sure what else could be causing this and it’s really inconvenient for me trying to download apps that I need
