I think it signifies a status change on the IRS's end but not enough progress yet to determine the outcome.
My status updated to the same message yesterday so I did a search of the text string and found scenarios ranging from the status updating to refund approved and a deposit date to various errors with various actions needing to be taken to resolve the errors.
I am now checking for my 2019 transcript on the IRS's get transcript site to keep track of what's going on as well as the where's my refund page.
I hope this information is helpful.
