Changing platform.openai.com default org doesn't affect chat.openai.com

Hi, I’ve recently signed up for a free account on both openAI platform and chatGPT. Then, with the same email, I’ve been invited into my organization paid account (tier 4).

Now, changing the default organization in platform.openai.com, I’m able to access all the paid features there (GPT-4, ecc.), but when I login into chat.openai.com my organization paid features are not exposed (I can’t use GPT-4, nor creating Actions, nor GPTs), only my personal account is recognized.

How can I switch the default organization associated to my account in chat.openai.com?
