You're missing the point, your (Intuit) system DOES NOT WORK, instead of throwing your hands up and saying, "well our system is broken so don't use it." why don't you actually FIX the underlying issue. Note that the same is happening with STASH. Inputting all the information correctly for both WeBull and STASH and both fail to connect saying I'm typing in information incorrectly. Also, per other's suggestions, I couldn't get the Apex Clearing "trick" to work. Intuit fix your system and stop telling us to "just import it manually."
