i can´t find a way to reproduce, Google logged out my account, getting lots of warning for 2FA verification after logged-in. I have to change my password because Google blocked my account. I thing Google is flagging Orion like a modified version of Safari, and turning a "non-official software" warning.
i'm using safari user-agent for compatibility, using ublock origin extension, adguard extra and others opensource extensions.
Orion Version 0.99.124.4.1-beta (WebKit 616.1.14.11.1), macOS Sonoma
