Hi @Garrett Dribusch ,
Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.
We have a received a response from the backend team, they said:
The published docs were incorrect and have been updated. You'll need to split your job into smaller pieces of work that can run under 2 days. This is a hard limit in Azure DevOps by design and not on our pools.
Unfortunately, you'll have to run these jobs in smaller pieces under 2 days.
