Users who belong to more than one private category are complaining that search only works for one of them. I can recreate this on my own admin account. Is this a bug or is there some setting I'm missing?
Can you give me a few examples of what you are expecting to happen in your search results? I can spoof into a few members and try to recreate the issue. If you want to link us to some threads/sections privately, feel free to submit your ticket via email by sending it to firstname.lastname@example.org.
