Further we would like to inform you as of now downloading is not working in roaming network due to Google and Google is working for the next update to resolve the issue.Also the relevant department may serve you better/speedily, if you can provide logs by registering this feedback in Error Section (Samsung Members App -> Feedback -> Questions/Errors -> Create -> Error reports).
