Unusual Siri behaviour

Hi, i'm facing an unusual issue with Siri and I hope that I might be able to get some answers from this forum.
Are am using an iPad Air running iOS 10.3.3 and an iPhone running iOS 11, and the issue I am about to describe occurs on both devices.
Normally, when I ask Siri to search Google with a particulars search query, it will bring up the Google website in the Safari browser with my query in the search box and a list of results below.
However, for some reason today when I asked Siri to search Google It responds with " here is what I found on the web" followed by a list of results provided by Bing, not Google even though I specifically asked Siri to search Google.
I have tried changing the preferred search engine but this doesn't seem to have any effect.
I am wondering if anyone else is having this issue, I would like to try and respond to any questions I receive here but I'm having trouble changing my password to login, and the link I'm using now is only valid for 24 hours.
Thanks for any help or feedback you can provide.
