I recently had a similar experience with Robinhood. I found that if you use their "Logout all devices" feature, you have to re-verify your account with them. They allow you to deposit and place trades, but as soon as you attempt a withdrawal, they notify you that you have to re-verify your identity with them. After two weeks and three denied attempts to verify my identity, I got the SEC involved. Within minutes of the SEC notifying me that they contacted Robinhood on my behalf, my account was verified without further action from me.
I withdrew all funds, closed all positions, and deactivated the account out of principle. It shouldn't take SEC action to get access to your funds. And Robinhood shouldn't notify their users that identity verification is required only when a withdrawal is attempted.
Robinhood obviously isn't FAANG, but apparently this is the progress in tech more generally.
