Investigating
Later's teams are aware of behaviour within the Instagram API that has been causing Reels scheduled to Auto-Publish to not process correctly. This issue appears to widespread with a number of other Third-party developers reporting the same behaviour.
Meta has been made aware of this and we are currently awaiting an update from them.
Reels scheduled to publish via Notification are unaffected. This method will be the best workaround until expected functionality is restored.
