Pro $200/month user - option for Astra is gone!?

After the latest update, If I create a new chat, I can only pick 'Latest' or GPT 5.6 Sol or GPT 5.5.... and 'Latest' gives me GPT 5.6 now. Old chats still show Astra where it was selected, and completely different choices, but new chats I'm not allowed to use Astra now. What on earth is going on?
