I have a projected assignment on ACT but nothing is showing on my ERB, is there a specific reason for that?

It should update by the next EDAS cycle, usually Tuesdays

I’m in the same boat, won’t show up on ASK neither but my YMAV changed. Once your sponsor does his part 3 you’ll be good.

Takes a few days, they don't all show up in the same places right away. Rely on your email for assignments, projections are just that. It's the actual paperwork and official emails that mean something.
