Other Postloop problems
Analytics export omits the last day of the range
Selecting 1–31 August exports through the 30th. Off-by-one in the range boundary.
Editor role cannot reschedule a post they created
An editor can create and submit a post but cannot move it once it is approved, which forces an admin into every small timing change.
Bulk CSV import silently drops rows over 280 characters
Importing a 400-row CSV produced 361 scheduled posts with no error. The dropped rows were all long-form LinkedIn copy.
