I was rejected 3 times before it finally told me that the system needed to update itself and told me to check back after February 24th. I resubmitted it for the 4th time yesterday on the 26th and was finally approved by MN this morning (Feb 27th). It said the system needed to update itself. I am not sure why it is was happening, but it seems to be resolved on my end. Hopefully yours has updated and you can resubmit as well!
