I read similar today, but as with most things Brexit it's not entirely clear. The data exchange has stopped but theres some other way they could conceivably get what they need:
"It is understood that while the Cross-Border Enforcement Directive has been scrapped, the 1959 Council of Europe Convention on Mutual Legal Assistance in Criminal Matters will continue to apply to the UK.
That raises the prospect of continental prosecutors still being able to access the details they need to trigger proceedings, but via a different route"
