I’ve started with Mattermost this week and i use Ubuntu 18.04.1 with docker. It works fine accept for the team logo. I’ve customized it to our own but it won’t show as you can see below.
I’ve checked if the .pgn file is in the directory and i found it in /usr/mattermost-docker/volumes/app/mattermost/data/teams/longstring/teamicon.png
It look fine and the .png file in de dir also changes when i change the logo in the gui.
