They are forever trying to recover from the very worst 'own goal', Netflix and Spare etc. Their extensive and expensive PR efforts are continuing to kick that ball back into their own net, it's getting them nowhere, except continued ridicule.
I think they really believed they would be elevated to another level of celebrity beyond the RF, while at the same time hoping to destroy the reputation of the RF and the UK, especially William and Catherine. In fact, they have managed to do the complete opposite, and not only in the UK, the RF are even more popular with the public while Harry & Meghan are left relying on some crazies for public support and desperate PR spin by paid spin doctors.
They are not welcome anymore in the UK by the majority of the British people, they shouldn't be invited to any RF public events.
