BOI: Your legal documents are being reviewed. How long will this take?

Just received this notification:

"Your legal documents are being reviewed. There are several review stages, so we appreciate your patience. "

This is the stage where all the documents from my solicitor have been uploaded/submitted including the payment request. Every documents that I'm responsible for are also already uploaded and accepted.

So how long will this "review" take? Any recent applicants from BOI, can you share your timeline on this particular stage please? Thanks!
