Are you sure is only since 3-4 months? If that is true, you might be banned for violating rules, but as I can see, some of your recent photos and videos are public.
Myself and many others experienced a change exactly 13 month ago (on the day 
). See this extremely long thread.
To be more precise: views are appearing later and many photos posted after Feb 7, 2024 don’t show any views until today.
One change, we did notice, is the “one percent rule”, i.e. the view count only changes if the delta is more than 1% and greater than 5.
