Implement JET filetransfer for OMEMO
(I think this might be a sort-of-duplicate, but I'm not certain. I apologize if it is.)
I chat to a friend in a one-to-one OMEMO connection.
I'm on Windows 10, Gajim v1.1.3 with OMEMO plugin v2.6.29; GTK+ v3.24.1; python-nbxmpp v0.6.10.
They're on Android 9 (I think) and Pix-Art Messenger v2.3.4-playstore.
Server is Prosody v0.11.3, with XEP-0065 enabled via mod_proxy65.
I can send images to them (Gajim online/offline upload-not-available bug notwithstanding). They can download and view the image fine. If they send me an image, I can download it, but I can't view it. It appears to be still encrypted.
Have I misconfigured something? If not, how can I work around this?
