One thing I had to do on the Morgan Stanley side was disable and reenable Third Party sharing under Security Settings to solve one import issue I am having. Thank you to the MS help desk. Also may want to follow the "2024 Tax Year import from Morgan Stanley tries to connect then just beeps. No errors, no import" thread; many more people in this boat. I was able to import once (my date), but unable to import a second time (wife's) data from Morgan Stanley.
