On Android App: Selector shows “Flash 2.5” instead of “Gemini 3 Pro” (I have Google One AI Premium 2TB)

I'm confused about the model availability specifically on the Android App.

I have the Google One AI Premium (2 TB) subscription, which should include access to Gemini 3 Pro (Gemini Advanced). However, when I check the model options on my phone, it's stuck on "Flash 2.5" and I don't see an option to switch to the Pro version.

I'm attaching a screenshot to show exactly what I'm seeing in the menu.

Has anyone else faced this on Android? Is this a UI bug or do I need to change a specific setting to enable the 3 Pro model on mobile?

Thanks!
