@Apple This is extremely disturbing

[Lee Cohn @lncohn]

So I tried out the @Apple savings account. There is currently no way to move money out of that account because the external account verification process requires you being on hold for 3+ hours. I've tried this three times already.

[Lee Cohn @lncohn]
