I have a course hosted on a MoodleCloud site (the 'Tool' in LTI 1.3 speak) that is accessed from a customer's self-hosted Moodle (the 'Platform') as a course-level LTI activity.
When displayed on the Platform site, when logged in as a student the Moodle header bar (Home / Dashboard / My Courses etc) from the Tool site is still displayed so the student can navigate out of the course. I gather the correct behaviour is that this header bar should only be displayed for teacher and admin users logged in with LTI, but for students it should not be displayed. See screenshot snippet below.
I can use the force_embed=1 configuration in the LTI Tool settings on the Platform to hide the header for ALL users, however that's not ideal as this method also removes not just the site header bar but also the course left navigation block and course user menu, all of which should be retained for the student. See snippet below.
I have a self-hosted dev site running the Classic theme that has the same behaviour, which is what these screenshots are taken from. The Tool site is running the Boost theme. I can only think it's some kind of theme issue but not sure how to troubleshoot it and am trying to avoid the cost of hiring in a developer, hoping it's some kind of config issue!
Any help very much appreciated
