As of June 15th, 2019 the data import of stock prices is not working. This is due to a change in the way stock quotes are accessed. A fix is in progress and will be submitted to the Mac App Store once the fix is complete and tested. In the interim, please manually enter prices. UPDATE JUNE 24 — The problem has been fixed and is being submitted to the Mac App Store. Thank you for being patient while this issue is being resolved.
