Messages sent from Thunderbird / Enigmail not visible in DC

I have DC on my phone and Thunderbird / Enigmail on desktop. I transferred the key from DC into Enigmail using autocrypt setup message.

When I send a plaintext message from Thunderbird, it shows up normally in the recepient’s DC.

But when I send an encrypted and signed message from Thunderbird / Enigmail, the message does not show up in DC at all. The recipient has no idea that I messaged them.

The message does show up in their regular email client (gmail). But it’s encrypted, and they don’t know what to do with it.

On my end, I can read the messages that I sent just fine.

Are there specific Thunderbird / Enigmail settings that have to be set a certain way?
