Consider that you have configured the LTR Backup for your Azure SQL Database and you are not able to view it on the Portal.
Figure 1: LTR configure policies pane
And when you click on available backups you do not see the list of backups.
Figure 2: Available Backups pane
This might be related to a permissions issue on the subscription level. Basically, the LTR Backups are related to the subscription and not the server, so if the server was deleted those LTR backups would still exist as they are associated with the Subscription.
Now to give yourself permission to view and restore the LTR backups, please make sure that you have one of the following permissions on the subscription level:
Subscription Owner or
SQL Server Contributor role in Subscription scope or
SQL Database Contributor role in Subscription scope
