Hi. I’ve had success with dino from backports. I can sign in, add contacts and have conversations. OMEMO works with other dino im users, but the people on Gajim cannot exchange keys with dino. Apps have nuances in how they implement OMEMO and it’s causing breakage across the ecosystem.
Can’t post links.
Google the article OMEMO is broken in general across the ecosystem on monal’s blog.
There aren’t any OMEMO clients on MacOS or iOS that are bug free and easy to use. Some servers like jabber de have a web chat feature with OMEMO running in a browser.
