Hi everyone,
My boss created and sent social posts (LinkedIn) on D365 marketing some days (5days ago).
The marketing team tried to create a post today and send it out to social media and they got an error.

Initially, I thought it was a permission issue, I ended assigning the marketing guy a Sys admin role but the issue still persists.
I have personally tried to post it and I got the same error.
Any help is much appreciated.
