I saw reports of this elsewhere yesterday night here in the forums (sadly can’t find the link right now), but pesonally I had no issues. Both internal and external views worked as they used to (holding right click+mouse or middle click for a perisistent camera view). But clearly something must be off if several users have reported it.
You might want to check this though in case some setting went rogue: Cannot use the right mouse button in the cockpit view, outside view works
edit: ah I probably saw this last night I can't look around in the cockpit anymore using the hat keys or the mouse
