Uber and Ordering a Ride via Siri

iOS & iPadOS

I was able to use siri to order a ride with 'Call Uber' this stopped working and I found I then had to say 'get Uber'
This has now stopped working, and siri appears to think about it for a while and then tells me that I have to continue through the app.
I tried with Get me an Uber home (and I have got home as a place within the app) and it still doesn't work

Does anyone know if there is a different phrase that I have to use?
