Cortana may have appeared briefly uk

[Lumiamike]

Was just doing a search on my phone using Bing in the Uk and I got a page of results that looked just like Cortana results which look different to Bing results, also at the top of the results page I had large ads for something Chineese ?? Can't repeat and missed a screenshot but for sure it was a Cortana looking result. Anyone else seeing oddities ??
