This was not issue, rather question "How this feature was changed", as I was not able to find how this work in v1.10Currently I find how to do that.The problem was in my understanding how new "Advanced search" works and a little problem with translation to Polish language.So the solusion is:1. Click in "Advanced search" in Tickets tab2. Check checkbox "Assignee"3. Select "inlcudes" in combobox 4. Type>>Select Agent Name in EditBoxBtw.I find the word "Assignee" on crowdin, and I change aproved string, as my previous aproval for this string translation was incorrect.
