It's unclear what accolade you're referring to here. If it's the 'max silver' accolade, and you're using Resonant Evil as an example, it should only trigger upon hitting max with a silver character. If you maxed out Resonant Evil before the update, you would not trigger this accolade. The only accolades that will trigger based on pre-4.3 progress are the story mode related ones and player level, since they can only ever be achieved once.
