When family organizer updates payment credit card, members of family still only see old card on file. Payment declines with no other options!

Here's something that may help. I had the same problem. On my phone I am the organizer of a family sharing setup for my family under one AppleID account -- let's call it AppleID account "A." However, for my personal iTunes store account I use AppleID account "B," which I created 15 years ago -- in pre-iPhone days -- for use with iTunes music purchasing and the iPod. The reason I still use this account is that all my music purchases are tied to it. Now, back for Family Sharing. When I created the family sharing setup, it allowed me to choose the account for purchase sharing. Here's the important part: I chose account B for this. I had a helpful online chat with Apple support and they pointed out that in order to change the payment method for account B I have to be logged into that account. On the phone this is a hassle - signing out of iCloud and into another account would have messed up all my settings. So I logged on the web at appleid.apple.com to account B and changed the payment info. I had already turned off Purchase sharing on the phone as part of trying to fix this. When I turned it on again and tapped through the "Set Up Purchase Sharing" flow - the updated card information was reflected correctly. Hope this helps anyone out there that may be facing this issue.

Did anyone ever help? I'm in the same situation. My cc was skimmed, I cancelled it, got a new one and now can't chance the payment method on apple. No way to select it. Not from Mac or iPhone. It's a mess. One more nail in the coffin for Apple. I've been migrating to Google over the past few years, and this might just push me off the edge. If anyone from Apple reads these, HELP before it too late for your company. You may just lose it all for not caring.
