Hey Loppy22,
Sounds like you've been on a bit of a wild goose chase, and that's definitely not what we want for you. So after having a stickybeak on our end, it looks like the OIP that was cancelled isn't actually the one linked to your active invoices— which is why it's still showing up as live on your side. Bit of a mix-up there, and we're sorry for the confusion. Just a quick heads-up too: if you'd already sent out invoices before disabling online payments, those old ones will still have the payment link active. You'll just need to re-send the invoices so they're refreshed with the correct settings, and let your customers know to use the new ones to make payment. You can also check this link for more info.
Cheers,
Doreen
