I’m not sure what is going on, I have tried disabling a bunch of Chrome extensions incase they were conflicting, but that hasn’t worked. It seems to be a problem on my colleagues computer too. Anyone have a solution? Manually typing which project a task needs to go into is very time consuming instead of dragging. I cant keep working in incognito mode, it looks suspicious 
Hi @danwallem! You’re not alone! We’ve chatted about this in the following thread: Anyone else as bummed out as me that we can no longer drag tasks from project to project - Tips and Tricks - Asana Community Forum
I suggest you take a look at this thread, specifically Kaitie’s comment, and follow up in the thread if you have any additional questions. We’re happy to help!
