Thanks for your reply.
I use passbolt/passbolt:2.12.1-pro-debian with firefox 76.0.1 (64 bits) or chrome Version 83.0.4103.61
I use the exemple kbbx found here : Passbolt Help | How to import passwords from a csv or kdbx file
If no modification the import works but if if create a simple group et move a credential on it, the import don’t work. No action when i use the import button.
No error message in the console or in the container logs.
