Hey @rosics-code, thanks for bringing this up. We can't revert directly here, as useRouteMatch is deprecated in react-router v6 . Ideally we'd want to resolve this with minimal changes from the code currently in master. I think the likely culprit here are the changes in how the styles are passed to the NavLinks
