Attempting to download an attachment with an unknown file extension results in an error message saying: Your device cannot open this type of file.
In my case this is a problem because I want to download SSH keys to my device and then use Termius to import those keys.
I think there should be a download button as well as an open with button so that it’s possible to download attachments with unknown file extensions. This would greatly enhance the usability of Bitwarden attachments on mobile devices.
