Congratulations on getting a lot of views on your Facebook Reels videos! As for not receiving stars, there could be a few reasons for this.
Firstly, receiving stars is not a guarantee for every video. Stars are a way for viewers to show their appreciation for content creators, but it ultimately depends on their willingness to give them.
Secondly, it's important to note that Facebook Reels is a relatively new feature and not everyone may be familiar with how it works. Some viewers may not know how to give stars and may need some guidance.
Lastly, it's possible that some viewers may not feel inclined to give stars if they believe your content is already being shared or reposted elsewhere without your permission. While it's understandable to want to remove the TikTok watermark, it's important to ensure that you are not violating any copyright laws.
Overall, keep creating engaging content on Facebook Reels and continue to promote your videos to your audience. With time, you may receive more stars as more viewers become familiar with the platform and its features.
