Hi @Kurunglu ,
Greetings from McAfee,
We would like to inform you that as mentioned in the KBdoc, any files that you currently have inside a Vault must be moved out of the Vault before February 2022.
You can export your data from the vault and store these files in one of the other popular secure file storage systems that are available.
You will also find an option to delete the vault after you sign-in to the vault.
For further assistance kindly do reach to our McAfee consumer support by accessing the below link
