This is my first time asking a question in this forum. I'm not a native English speaker so please forgive my grammar mistakes. The situation is like this: When I saw a post in the news feed, I clicked into one of the post's author and clicked into the comments. In the comments, I clicked into a photo comment. When i click the back button, which it was supposed to go back to the comments in the author's page, it went back to the news feed. My phone is a LG K10 and I'm not sure whether it's a Facebook bug or something else. How can I solve this issue?
