Hello,
In the previous version of Logi Options, it was possible to disable screen corners as active zones for Logitech Flow.
This option is missing in Logi Options+, and currently there's no way to prevent accidental screen switching when the cursor reaches the corners.

I’ve also tried using the “hold Ctrl to switch” mode, but sometimes it causes issues where it seems like the Ctrl key remains pressed, leading to unexpected behavior in other applications.

Please consider adding back the option to disable screen corners directly. This would provide better control and avoid accidental transitions.
