Fully import Keepass database including attachments, whether pictures, docs or other files. I cannot switch from Keepass to Proton Pass until the import is complete. Import must also clearly report any item that cannot be imported successfully without any corruption. These are security details that may lay hidden for years ... until you need them. They must be there at that time, for me or beneficiaries.

I did search requests (unsuccessfully) for import of keepass attachments before requesting.

The Keepass XML export includes all attachments, compressed. Proton Pass should import these without any corruption.
