Just to let everyone know I will be requesting the CA PPM sandbox to be upgraded to 15.1 in the latter part of November. Once I have negotiated the exact date, I will let everyone know.
It will be a fresh build so we can see everything from a "native" install perspective.
For those of you that have been using the sandbox, thank you for being respectful of everyone else. We only had one issue where the project object was messed up and causing errors. I resolved that this morning. And I received no complaints from any users about any other users.
