Help with If statement with And and OR included

[AlGrant]

I'm trying to flag items in our app tracker list as at risk (Yes or No) based on timeline and running into problems. FYI - I am new to Powerbi. 

I have a list of items with Status column and a Start Date column. I want to flag items as At Risk if they are not "complete" or "In Progress" and are past their start date. I would also like to flag items as as at risk if they have a blank start date and are not "Complete" (In Progress or Not Started).

Below is what I have so far, problem is that "In Progress" items that have a blank start date are not being flagged as at risk.

At Risk start date (y/n) = IF('CMI Application Tracker'[Migration Status] = "Not Started"

    && 'CMI Application Tracker'[Migration Start Date] < TODAY() , "Yes", "No")

Thanks again @grantsamborn for helping out on my last help request...this is similar but unfortunately I was not able to adjust and get it working.

Hi @AlGrant 

Can you give this a try?

At Risk start date (y/n) = 
IF(
    ( 'CMI Application Tracker'[Cloud Migration Status] = "Not Started"
        && 'CMI Application Tracker'[Migration Start Date] < TODAY() )
    ||
    ( 'CMI Application Tracker'[Cloud Migration Status] <> "Complete"
        && 'CMI Application Tracker'[Migration Start Date] = BLANK() ),
    "Yes",
    "No"
)
