I shared five links with a Basic account, all of which were supposed to expire tomorrow (29 April 2025). However I received an email today notifying me that they hadn't been downloaded yet. In response, I upgraded my account to a Standard plan to extend the expiration date. But now, all of the links have disappeared. I can't find them in the bin, the expired section, or anywhere else. Even when I try to open the file by clicking on the 'Manage Transfer' link in the email I received when I originally shared it, I just get an empty transfers page. I'm extremely frustrated and upset. Please help me!
