The toggle that previously let admins disable Gemini 3.5 Flash is gone. Every user in the Gemini Enterprise app now runs on 3.5 Flash whether they want to or not — the choice has been made for them. If your org had that toggle turned off for compliance, testing isolation, or cost reasons, that configuration is now irrelevant. Worth auditing any workflows that assumed the prior model version, particularly if behavior differences between Flash generations affect your pipelines or integrations.
