Hi there. I live in the UK and need to get a replacement remote control for my 3500X streaming stick.(I know it's the remote that's faulty as I can still control the stick using the Roku app on my smartphone).The remote model is RC 28 and the p/n is 3226000093. Roku's accessory supplier only lists a remote suitable for the 3600X and neither they nor Roku can tell me where I can get one that will work with my 3500X. Can anyone help please?
