I don't know if it has anything to do with the new "and improved" jira but the avatars of my team members are gone. We always worked with avatars so you can directly see on your board who is working on what. Now this is changed to initials even though the pictures are still there if you look at your own profile
There was an incident involving avatars on Cloud, which has since been resolved: https://jira-software.status.atlassian.com/incidents/jnygk8kr6f1t
I recommend to "Subscribe to Updates", so you will get notified if Cloud is having any incidents.
Can you check again?
Hope it helps,
