@greencrm - I was not able to reproduce issue with latest master. I had (admin, userA, userB).
Step 1: As admin created filter and shared with userA
Step 2: As userA I could see the filter shared. (Expected)
Step 3: As userB I could not see the filter (Expected)
I use demo.vtiger.com for record this video. Issue was not related to browser or other client side stuff, we test with many computer with different OS.
@greencrm - thank you for the access, I wanted to confirm if the setup missed any core table. It did not. The focal point of the issue - condition part of the filter not being applied when using shared list.
