thoroughmas Thanks for the feedback! For E2EE to function properly, both encryption and decryption need to occur on the client side (in the browser). As such, it is possible to implement single-entry export. However, for bulk export, the client may not be able to handle large archive sizes. As such, the bulk export is implemented on the backend, and it cannot be decrypted there.
But do not worry, I have already sent this feedback to my team.
