I have a 2017 Hyundai Tucson and the auto stop-start button has a light on it at startup and the light on the dash is amber permanently. When I press the stop-start button nothing happens, the light remains on. None of the stop-start functions have worked for a while but I put that down to not driving a lot during lockdown. I’m now beginning to suspect there is a fault.

Start-stop issues are common with a lot of cars and we get many queries about it. If your car is not being used much right now, then the battery may not be in great condition and that's a leading reason for stop-start problems. It could be something else of course. Your car should still be under warranty if you want to talk to your Hyundai dealer about it.
In the meantime, read Why won't my car's stop-start system work? on the subject.
