Can’t add to watch list

[marcmocer]

Little by little the amount of items I could have on my watch list kept going down. Now I can only have 1 item in my watch list. Why is that?!? I tried logging out and back in and still nothing

You should be able to watch up to 300 items on your Watch List. That includes both active and ended items.

Do you have many ended items on your Watch List? If so, try deleting some of those to make room for more active items.

It might be easier to check your Watch List using a desktop browser to make sure you are seeing all the items on the list:
