Part of the challenge as I see it for H&M is that their previous worlds (hollywood/acting and royal family) were in different and contrasting ways very contrived and worked by everyone knowing the rules of the game.
For Royal life the contrivance relates to knowing who to walk behind, what to defer to staff, not having to do the admin of life, not needing to immerse yourself in masses of work around getting something going - partly because the system was so old. Some of this contrivance is superficially helpful (who wants to do the admin of life) but its limiting. A royal can glide in (in the right processional order) like the proverbial above the water swan, whilst unseen people in shades of grey suits are kicking like crazy. Sometimes the contrivance knocks you - for example (if we're to believe) KM lost a housekeeper because the housekeeper couldn't do their job because KM wanted to get in amongst the admin of kitchen life. Sometimes the contrivance is tone deaf (see mostly PA intent on sticking to his (self identified) place in processional order.
For acting/hollywood, the contrivance is about creating the best opportunities for yourself through maximising your image and capitalising on connections. Faux-romances are set up to maximise young actors appeal to audiences. Acquaintances can be super charged to be friends when needed. Everyone knows its fake but the rules of the game mean everyone plays along.
Although both contrived worlds, as separate bubbles they can (just about) work but bringing them together illustrates the contrivance in different ways.
Adding to that, they are now finding themselves in a different space - philanthropic activism, a desire to be global agents of change which will have its own set of rules/contrivances But I'm not sure they have fully grasped what rules mediate this space. There isn't a historic infrastructure, they have to build the foundations and that takes time and effort (a challenge if you come from a bubble where others routinely do the life admin). There are different routes to creating opportunity and maximising connections - (a challenge if you've previously had to self propel your own image and opportunities) Are their advisors - like SS confident about the rules of this new space - if not then there may be more 'clashes' as the three overlapping spaces they occupy brush up against each other.
