If you accidentally like and unlike a post on Facebook, the person who made the post may not be aware that you liked it in the first place. This is because when you like a post, a notification is typically sent to the person who made the post. However, if you quickly unlike the post, they may not receive a notification on their phone.
It’s important to note that Facebook’s notifications can sometimes be delayed or not delivered at all, so there is a possibility that the person might still receive a notification even if you unlike the post immediately. However, the chances of them seeing the notification and realizing that you liked and unliked their post within a short span of time are relatively low.
Additionally, Facebook does not keep a record of the posts you have liked and unliked in chronological order. So, unless the person actively checks their notifications or happens to see your like before you unlike it, they may never know that you initially liked their post.
It’s worth mentioning that if the person you accidentally liked and unliked is closely monitoring their notifications or has the habit of checking who likes their posts, there is a possibility that they might notice your action. However, this is relatively uncommon and most people do not actively keep track of who likes their posts.
If you accidentally like and unlike someone’s post on Facebook, the chances of them knowing about it are low, especially if you unlike the post quickly. However, it’s important to keep in mind that Facebook’s notification system can sometimes be unpredictable, so there is a small possibility that they may still receive a notification.
