I want to turn off the looming Shop Pay installment plan but I'm being stymied by a lack of a control box.
The sidebar in the Payments control panel says: "Your store accepts payments with: PayPal Payments Standard and Shopify Payments." but I don't see any way to control or configure Shopify Payments options, that box is missing from the list.
I contacted Shopify Support directly and that person said to turn PayPal off and back on again. Then I was able to adjust settings for both Shop Pay and PayPal payment processors. I did have to log it back into Shopify. Annoying, but that only took a minute.
