Amazon: I've checked with our Primevideo internal team and found that Amazon is available in Roku device in greece it is just the Roku Appstore doesn't have the app added to it, Amazon has no issues with the Roku in your location request you to please manually contact Roku Customer service to check with them because Amazon doesn't have control over the Roku Appstore
Me: From what I understand from Roku's reply "channels may not be available on your device in that location, based on each channel provider's discretion"
Me: are you tell me the opposite?
Amazon: There is a primevideo app available for people at your location, I've checked with our internal team its Roku appstore which doesn't have the primevideo app. It t might a small patch updated needed from Roku and it should fix.
