Cannot redownload watch faces

Not sure whether this is correct category, but it is Galaxy Watch related…

I have recently received many complains that user once changed watch (or reset the watch) and cannot redownload our watch faces and need to repurchase again. What happened and what shall we suggest them to do?

Thanks!

Hello
That user needs to sign in to his or her account with the same account and credentials and all his
watchfaces purchased should be available for download, sometimes it might appear that the dollar amount might show up , but it will change and allow you to download without going through the process
of buying the app again.
