I upgraded recently. Now when I am opening a new email, I get the following error:

E04D6E8BBD2BD871D638D087C133E870A73BA637: übersprungen: Unusable public key
gpg: [stdin]: encryption failed: Unusable public key

I should be able to write an email without the error message popping up.

    I found the error on my side.
    My keys were outdated so I renewed them but didn't realise I have to also update the subkeys by going into the detailed view of my keychain and selecting the third tab and from there the gear…
    Happy New Year & thank you for your work
