ok, strange, and maybe you can help educate me. so as i stated, the same key worked fine signing wise from the gpg or gpg2 cli. so i went ahead and instead tried importing an older backup of the same key i had on disk into rainloop and now it works fine. i removed said key from my localhost's gpg keyring and re-imported the older backup via gpg cli and it seems as it did before. so I'm confused. why did it work this time?

i had also tried exporting the prior key from my keyring, removed it from the keyring, and re-imported it. the same ascii armored text as i tried in rainloop. and it worked in gpg cli but not rainloop.

??? Thanks for any insight you can offer.
