When swapping libraries figma only swaps styles and components that are named exactly the same. If you have named components with spaced between “/” like so: “Alerts / Error” it will not match “Alert/Error” when swapping libraries.
It would be nice if the spaces adjacent to the “/” in names are stripped when figma tries to match the components. Or figma tries to find components/styles with spaces and without, So you get an option if there are two matches.
With huge libraries and many of them, Its a pain to go through them all and rename styles and components correctly.
