Hi @DigitalProgress ,
If the current URLs are performing well in terms of traffic and rankings, it's generally better to leave them as they are. Changing permalinks can cause a temporary drop in traffic unless proper 301 redirects are implemented for every affected page.
If the URLs are truly problematic (e.g., causing issues with SEO or user experience), ensure you map out redirects carefully to minimise the impact. Ultimately, if the structure works and there's no major issue, sticking with it might be the safer option.
