No PayPal on iTunes?

From 11/01/18, I received a notice that my iTunes payment option needed to be updated. Upon signing in I found my PayPal payment set-up had been booted. When I tried (numerous times) to reactivate my PayPal payment option, I only got the notice that stated “This payment option can’t be used in the iTunes Store”. I’ve only ever used PayPal with the iTunes Store, for years now. What happened? Is PayPal being fazed out? PayPal is still stated as a payment option on the Apple store website, so I’m perplexed. Please advise. Thanks!
