Upgraded iCloud+ storage not showing in Family Sharing

I have iCloud+ shared with my wife. I upgraded a few years ago to 50 GB, which is what shows up as shared with her. I am the administrator of Family sharing. This morning I successfully upgraded the storage account to 200 GB, but it isn't showing up as shared in Family. Only the original 50 GB plan is still available to her.

How do I get the new, upgraded storage to show up in Family Sharing. I would have thought it would have happened automatically, but for some reason the 50 GB plan is considered part of iCloud+ for Family, but not the new 200 GB. What am I missing?
