We are facing an issue when user1 and user2 simultaneously login to signage portal and update same campaign. Now user1 updates and save the campaign. Now if user2 tries to add content, and on click of save , user2 save won’t work and below error message is returned from signage server. User2 has to log out and login again to get latest data from signage server and then proceed to update. We need a fix from your side to refresh user2 portal homepage with latest data when another simultaneous user already updated the campaign.
