I have noticed this over the passed 4 years

I used to have 8 or 9 pages in my "Watch List".
Now i only have 4 pages.
No matter how much i add, its still just 4 pages

Worse, things i really want to buy have just disappeared from my Watch List?

Do items disappear if the seller removes them for sale?

After a some Googling, seems a lot of people suffering the same issue, items just going missing from Watch List.
What makes it worse, i have items in my Watch Liust for 8 years ago i have no interest it, yet they don't go missing

Anyone else suffer this?
