SmartThings routines and alexa app

My routines have stopped working with Alexa? They worked fine but now says in the Alexa app disabled because it contains unsupported devices? Lifx bulbs and Samsung plugs which are compatible?

Do you have motion sensors?

Yes but it’s not used on that routine

Are you using askAlexa or just the intgration from Alexa itself?

Integration from Alexa to run my bedtime routine. I’ve worked it out now, Alexa won’t except any routines with SmartThings home monitor in it. This is strange as it’s been working fine since I’ve had it.
