Hello,
I am a Google AI Pro subscriber using Google Flow with Nano Banana Pro.
Since 15 July 2026, I am getting “This generation might violate our policies” on harmless commercial portrait prompts.
Examples that WORK:
A red apple on a white background.
Portrait of a smiling woman on a white background.
Examples that FAIL:
Portrait of a smiling woman holding a notebook.
Businesswoman in a modern office.
Woman holding books.
Farmer in a wheat field.
Couple portrait.
These are normal commercial stock photography prompts without violence, politics, sexual content, or harmful requests.
I have already tried:
New Flow projects
Short prompts
Incognito mode
Different wording
Waiting until the next day
Is anyone else experiencing the same issue with Nano Banana Pro in Flow?
Thank you.

Yeah, I have this all the time. I think it is a glitch. you may have to reword your prompt to get it working again

Thank you for confirming. I also contacted Google One Support, and they collected screen recordings, account verification, and reproduction steps.
