Unable to download apps - Payment Method Not Complete

Hey there bagofgroceries,

From the link above your post, it lists the steps to take if you have issues with downloading apps. One of those steps(the third one) leads to another link that explains to add a different payment method as the one your currently using is being declined. Here's that link for your convenience: If a message says 'billing problem with previous purchase' or 'verification required'

If you've already done that, along with following the other remaining steps in the link above your post, then the last step listed would be to contact Apple Support. Here's the link above your post just in case: If you can’t download or update apps on your iPhone or iPad

Cheers!
