Inconsistency in home_timeline.json


I just recognized that doesn’t return some tweets in my timeline (that however are returned from the the timeline of the user I follow:
What may be the cause of such inconsistency?


Browsing my home on I noticed that the tweets I did speak about are missing from there, too. So, it not an issue regarding the Rest Api.
Anyway, for me it remains a mistery why some tweets from an user that I follow don’t appear in my timeline.
