2FA App Store - Application specific passwords and FASTLANE_SESSION can't be used more than once?

Question

I'm setting up a pipeline with Azure, which works fine for the first time, but when I try to use it again it doesn't use the application specific password anymore.

Here's what I have done:

• Reinstalled fastlane.
• Created a new application specific password at App Store.
• Created a new FASTLANE_SESSION running the command spaceauth -u user@email.com on terminal.

It works once in a while, usually after reinstalling Fastlane.

Apart from this, the pipeline works fine.

Here's the output :

Any idea on what could be the issue ? I'm using fastlane 2.28.3

Thanks in advance.
