I’m not sure I understand the problem, I’m sorry.
You no longer have favorite notifications? But you saw them before? When were they from? Does this concern items « sold » in the meantime?
Basically, notifications appear on the phone, but not on the PC browser. When I click on the numbered red notifications, it displays « No notifications at the moment, » even though it works on the Vinted app on my phone. This has been happening since yesterday, when I think Vinted might have shadowbanned me for abusive reposting. I received an alert this morning for suspicions or reports.
