Unable to use profile attribute matching in recommendations

[Saif]

Hello all,

I am trying to set up a recommendations activity where I need to target the users who have visited pages belonging to certain sub-categories.

I have applied this inclusion rule but it doesn't work:

"user.lastViewedTenSubCategories" is a profile attribute which contains sub categories separated by comma.

Is it expecting the list in a specific format?
