Thank you for your respond!
Yes, I tried using both Internet Explorer and Google Chrome, but the issue remains the same. I also tried clearing the cache, but it didn’t help. From what I found online, many other users are experiencing the same issue, but I haven’t found a solution yet. The “Save” function doesn’t work only when choosing to exclude categories and exclude tags—all other options work.
If you could let me know how you recorded the video of your desktop, I could do the same and share it with you.
