The short answer is: this is normal — nothing is wrong.
Facebook and Instagram often have different content schedules in a campaign. Brands create channel-specific posts, which means:
The content may differ per platform
The posting days may also differ
Not every Instagram post has a matching Facebook post (and vice versa)
That’s why you may see something appear on Instagram first, while Facebook is planned for another moment — or has different content altogether.
You can always check the details yourself:
In the Embrosa App, you’ll find an overview showing exactly which posts are planned for each channel, including dates and times. If you want to adjust something, you can do that right in the app as well.
