You are using an iPhone 15 Pro Max with the latest updates, and while interacting with the ChatGPT app, you encountered an issue. The model selection screen shows GPT-4o as the active model, but you received a message saying that you need to wait 20 minutes for access to GPT-4o, with only GPT-4 currently available. Despite the app displaying GPT-4o as selected, this inconsistency indicates a possible bug or glitch in the app.
You asked for this issue to be forwarded to the developers, and I recommended reporting it directly to OpenAI through their support channels.
Feel free to share this with the support team to help them understand the issue!
