Costco App: from bad to worse

Forum
iOS and iPadOS

Has anybody here been able to use the Costco App? It was never exactly a prize-winner, but now, when I try to update my information in the app, I get the big bad bonk and can't find anything readable on the screen. Is it just me, am I missing something, or has this app gone completely inaccessible? Thanks for either helpful tips or at least confirmation.
