How can I easily view and manage my Send link links and the Receive files links?

You can view all of your Send link links and Receive files links if you navigate to the Account menu and click on Links.

On the left side, you can choose which links you want to view - the download or the upload links.

Here you can see all of the links you created, edit them by clicking on the pencil icon or remove them by clicking on the remove icon, as well as see their location and click on them.
