Hmmm, can you check a few things for me to help debug?
- On Chrome, please open the Developer Console and go to the Network tab, filter by WS (websocket) then go the Frames tab
- Looking to make sure that frames are coming through no problem
- If it's working correctly it should look something like this
- Can you check your Mattermost server logs for errors?
- Does refreshing the page have the posts stop pending?
- When you upgraded to v3.1.0 did you use a release candidate (RC)? If so which one?
