Not enough harvested Facebook posts
The number of posts in a Facebook timeline is generally unlimited. However, the number of posts in a timeline that a user can view is technically limited.
This limit is directly dependent on the performance capability of the browser accessing the timeline. From a technical standpoint, all posts (including comments and reactions) are saved in the browser’s cache. The number of posts that can be displayed simultaneously depends on system performance. You will notice this, for instance, when scrolling through the timeline becomes slower the further you “scroll down”. In some cases, reloading new posts can slow down considerably. At some point, it stops altogether.
This behavior is the result of how the Facebook website is programmed. SNH has no influence over this.
For this reason, SNH can only harvest posts that the Facebook website actually displays.
If this prevents you from harvesting important posts, please try the following workaround:
Harvest the timeline first without any comments and reactions. Following this harvest, perform another harvesting procedure with comments/reactions. Displaying comments and reactions has a dramatic effect on the Facebook website’s performance. If they aren’t displayed, much more of the content of posts can be shown and harvested.
Upgrading the system on which SNH is installed can increase the number of harvestable posts.
