hi, I have tried to upload photos to use as a changing background. As instructed I have downloaded the Prime Photo App. When the option to upload from Prime Photos is chosen on the Show device it simply searches then returns to the Home screen. The Prime Photo App is working fine on my devices without the £7.99 subscription. Do I need to have the Prime subscription for this to work, if so I will return my Alexa Show as this is not clear and is a massive additional cost to the initial purchase price. If anyone has this working I would love to hear from you.
