Gemini 3.1 (Nano Banana 2) fails with "Something went wrong" in AI Assisted Editor

I'm experiencing a persistent issue with the Gemini 3.1 (Nano Banana 2) partner model in the Photoshop 2026 AI Assisted Editor (Beta) with Firefly. It worked normally yesterday (Sep 24) but stopped working today (Sep 25) and has been failing for several hours now.

WHAT HAPPENS

Every generation attempt using Gemini 3.1 (Nano Banana 2) fails with: "Something went wrong. Please try again later." (see attached screenshot)

STEPS TO REPRODUCE

1. Open AI Assisted Editor (Beta) with Firefly

2. Upload a reference image

3. Select model: Gemini 3.1 (Nano Banana 2)

4. Enter a prompt (e.g. vintage photo restoration prompt)

5. Click Generate

6. Result: "Something went wrong. Please try again later." - no image is produced

WHAT I'VE ALREADY CHECKED / RULED OUT

- Internet connection is stable

- Generative credits are not the issue: 2,960 / 4,000 premium credits remaining (see screenshot), plan resets Oct 15, 2026

- All OTHER models work correctly: Firefly Image 5, GPT Image 1.5/2, FLUX.1 Kontext, FLUX.2 pro - only Gemini 3.1 (Nano Banana 2) fails

- Signed out and back into Creative Cloud - no change

- Reproduced independently on TWO different computers/accounts - same error on both, which rules out a local machine or cache issue

- Checked status.adobe.com - no incident currently listed for Creative Cloud / Firefly / Photoshop generative AI services

ENVIRONMENT

- Adobe Photoshop Version: 27.10.0 20260824.r.26 9d9635d arm64 (final, Release)

- Operating System: macOS 27.0.0

- Hardware: Apple M2 Pro, 16 GB RAM

- Plan: Creative Cloud Pro (4000 credits/month)

Could you please confirm whether this is a known/ongoing backend issue with Gemini 3.1 (Nano Banana 2), and let me know an expected resolution time? Happy to provide the exact prompt text or additional screenshots if that helps investigate.

Thank you,
