The posts on your feed are determined by your channel subscriptions and language settings. If you notice that some posts are missing from your feed, it's advisable to check the following:
1. Check your channel subscriptions
You need to be subscribed to channels on the platform to view content in your feed. Without any subscribed channels, there will be no content.
You can subscribe to channels by selecting Customize my feed under the Channel list.
2. Check your language settings
You can select the languages in which you want to receive content. If you choose to receive content in specific languages only, any content created in other languages will not be visible to you. If your feed is empty or some posts are missing, it may be because those posts are hidden due to your language preferences.
You can adjust your language settings in your profile to add other languages or choose to view content in all languages.
