I am experiencing an issue where the "+ Add" then "News Post" doesn't work for me. Using "+ Add" then "News Link" does still work. Page doesn't show the information it keep loading. Anyone else experience an issue like this?
Checked in my Office 365 tenant and add new News Post feature is working and doesn't have any issues currently. Please see the attached snapshot of the panel which you would get.
Can you close and reopen your browser and check please. If still the panel doesn't load, please clear your browser cache and login again and check please.
