On a v recent thread here (could have been even this one) it was mentioned that when Meghan was doing her last season of Suits, the palace said no to a scene so writers had to rewrite. I don’t know If this is true, but it would make sense to me that Meghan would have found it very had to continue acting because it is likely that the palace would have wanted to approve of scripts etc. At any rate, I think there would have been roles she could not consider, and that it would severely limit her choice.
And how would H&M have managed to remain ‘in’ with Harry a working royal and Meghan acting in Canada or US? Live on separate continents? hardly an advisable start for a new family. I don’t think that would have worked at all and, perhaps, that’s why Meghan vetoed it and made it known her intention was to be a working Royal and ‘hit the ground running.’
[To my mind, if the Queen had said Meghan could continue acting, as had been reported, the Queen was not being realistic. And she was a pretty realistic soul it seems, (except when it came to her favourite son).]
If you look at Meghan’s work history she had numerous roles and ‘Suits’ had really consolidated her career. There is no reason to think Meghan’s career was already over (as I’ve seen opined on mn a number of times). She was not a big name star, but she was a real, regularly working actor. So, those who say she’s Z list etc - well they are not correct.
