Keep in mind that the Client "Pix-Art Messanger" doesn't exists anymore. "Pix-Art Messanger" has been renamed to blabber.im - I think ~ November 2020.
1) Make sure you buddy is using the latest version of Conversations or Blabber on Andorid 2) You may already got 2.7.13-1 of the gajim-omemo plugin? ejabberd logfile may not help. The most part of OMEMO is on client-side. With a current version of ejabberd the PEP and setup of access model should be fine. -- Stefan
