Invites not being sent


I’ve recently been experimenting with getting a Bitwarden setup running on my PI4 and all seems to be working fine but I have an issue around sending invites.

Sending email does work as I can get verification emails etc but when I try to invite other users nothing is happening.

No failures are appearing in the logs.

Is this expected behavior or do I have some hidden issue in my config that I can’t figure out?

Any hints or tips are welcome?
