Prior review for OT | Collection Sort & Manage

I have been using this app for years on titanium plan. I have always been having issues with restocked products not being pushed up. I have reached out to support, first they blamed other app that i was using and after +10 emails back and forth finally they admitted their error and promised me to fix it. However it still has not been fixed yet, their solution they have provided does not work. Their support has also been unresponsive since 15th/09
