Anyone heard anything so far? We were told that it is not publicly available yet. No answer to the question on how some apps got the access already. I have also noticed that they disabled all the links in the documentation recently. https://developer.apple.com/documentation/financekit/financestore

Yeah I'm in the same boat. Called them a few times, escalated but no luck so far. Please keep me posted, I'll do the same if I hear.
