Can't decrypt encrypted.asc from Mail

[chriscapisce]

First off, thank you very much for this great app! I got an error after trying to send you an e-mail on dev@naef.lu Recipient address rejected: Address does not exist so I'll just ask here:
I encounter an issue, not being able to read the content of an encrypted message.
In Mail I open the encrypted.asc file and send it to PGPro. In the settings I enable undor Preferences “Mail Integration” but still no luck. I can read a bit of the headers but nothing of the e-mails content is being decrypted.
Any idea how to solve this?

I’m on an iPhone SE 2022, iOS 15.6.1 and the latest version of your app, 2021.4

Thank you in advance.

I see now you use dev@naef.app. The mailto link in your website's footer still points to dev@naef.lu..
