Hi @Robmclovin92 , welcome to the community!
Offline content is device specific, so if you have multiple mobile devices where you want to download your stations, you'll need to repeat the download process on each of your devices for the stations you want to download.
If you'd like you can share a new idea or you can take a look to other similar ideas, such as this one: Ideas: Restore offline downloads after reinstallation.
To express your interest in seeing this existing idea added to the service, I recommend upvoting this existing feature request with a ❤️, as well as posting a comment with your specific suggestion.
Let me know if you have any other questions.
