She was welcomed in the same spirit that any royal bride would be.. IMO. Ie some royal watchers who are very enthusiastic about the RF were really pleased and ready to welcome her.. Most people just thought of it as a royal wedding coming up and weren't that excited.. People IMO aren't THAT into the RF unless there is an event, like a wedding, or a scandal/big fuss like the war of the Waleses. I don't think that people were one way or the other with MEghan except for ardent Harry fans or ardent royal fans...but it would be the same whoever he married...Once she was married it was then up to her to do the job and see how she worked out, but while she did well at first and I think got some admiration and good press for enthusiasm, she also got criticism..But again that's to be expected.. Kate has gotten criticism and so did her family but a lot of it was in her courtship days and now she's settled into life and is admired for her low key but increasing work rate... and to be honest, with Meghan bowing out of royal life after little more than a year, Kate has the field to herself....
But Meg and Harry began to react badly to any criticism within the first year or so, and began increasingly it seems to do things that gave the press an excuse to have a go at them...
