Looking at the connections between their natal charts it mostly seems harmonious. However, both have their natal Mars in a square aspect to each other. This planetary combination shows a lack of understanding between the two duchesses. There is probably quite a bit of tension. In their royal duties, they need to work independently as teaming up with each other would bring impatience, irritation, and arguments. Giving each other space to pursue separate interests will be very important. Provoking a reaction from each other could be a big problem.
Meghan's natal Pluto is in a square aspect to Kate's natal Sun. Whatever happens, this relationship will have a powerful impact on both of their lives. Kate probably finds Meghan to be fascinating, intriguing, and even mesmerising. Meghan could sometimes feel threatened by Kate's displays of ego and pride. However she also has the ability to easily see Kate's strengths and vulnerabilities which, in turn, will make Kate feel defensive as she'll be aware that Meghan can see right through her.
This planetary combination of the Sun and Pluto shows that the nature of Meghan and Kate's relationship is very deep and hard to define, and unless they keep their distance from each other, there will likely be explosive moments between them. They could tend to draw out each other’s dark sides, and there may be battles of will between the two of them. Their connection to each other is very profound, and the challenges and drama produced by their relationship means it will become a particularly significant one.
Meghan's natal Pluto is also in a square aspect to Kate's natal Moon. This is a tough, emotionally intense aspect and as a result, the potential for many heated conflicts can arise.

This planetary combination symbolises fascination tinged with fear.

Meghan's natal Pluto is conjunct Kate's natal Saturn. This planetary combination indicates two people who chained together for some reason - in this case because of the restraints of royal duty and the fact that their husbands are brothers.

Kate's natal Saturn and Pluto are in a square aspect to Meghan's natal Ascendant. This indicates that she could bring Meghan a much-needed sense of structure and stability.

These two could have a ruthless attitude towards each other resulting in drastic upheavals and power struggles.
With Kate's natal North Node conjunct Meghan's natal Ascendant there would have been an immediate and powerful connection between the two women.

Like it or not, both of them will be responsible for the future success - or otherwise - of the British Monarchy.
