It just keeps loading. Maybe is a problem with the add-on AdGuard? How can I solve this?
Edit: I haven’t solved the problem, but after some time trying some things here and there, I think I know what’s the issue. I have both Chrome and Firefox installed. I was using Lemmy on Chrome, so I tried to login in Firefox, and the issue started. I logged out on Chrome, and tried here on Firefox, everything fixed.
TLDR: you can’t have the same account logged in on both Chrome and Firefox.
ADHD aside, you need to ask yourself if you like it, if you're really interested in the content shown, if maybe your mind is distracted in something, or you're worried/uncomfortable in the environment you are in and the likes. Have you read How to Read a Book by Mortimer J. Adler? the author explains that we learn to read just on a surface level, leading sometimes to problems like you express. He then teaches how to approach a book in a way that you squeeze the most information and knowledge from it, even if its just a fiction book; and in the process, remember everything that you read even after finishing it. What works for me is: give a conscious effort to concentrate in what you're reading, but don't stay in the same page, don't even read a sentence two times. See if you concentrate better with music; I have ADHD and when I read books I need to listen to three diferent playlists to concentrate. Finally, following the first thing I mentioned, giving a conscious effort is exhausting to the brain so when you realize you can't concentrate anymore just leave it and start again the next day where you left it, you will notice that your brain will stand more and more all the work out you're giving it.
