Hi,
I confirm that by default, I don’t have rotation with the browser. I went into Display Settings, modify default values to check everything. It worked. I came back to default configuration, and it worked too. So there is a strange behavior.
What is really strange is not having the rotation shortcut in the top menu. I create an issue.
@cm63 please also open a GitLab issue if the setting configuration does not take effect on your device.
