I have the US version. I had changed location to my UK address before the UK launch, and a few days ago changed the voice over to UK English. But since switching the voice to UK, my Alexa keeps randomly saying thinks... last night she all of a sudden said 'to turn on voice purchasing go into settings etc...'. Or I get a random 'I cannot find this in your play list'
While it was on US English, I only had that happen once in 2 months. Now it seems to happen nearly every day
