Something is a joke, but I'm not sure

if it's the new app, the app in general, or PF itself.

Since I signed up there's been an annoying yellow bubble in the app begging me to attach my credit card as a secondary form of payment. The other day I finally got around to adding it and wouldn't you know it? Despite the field saying Postal Code instead of ZIP Code it wouldn't let me enter my info because "it needs to be five digits". I assure you it doesn't.
