Account is restricted to liquidation only

Live trading, positive cash balance, DT number is 2 and not placing any daytrade orders, and I’m getting “account is restricted to liquidation only”. No email from you, no notice of any kind. What is it?

Later in the morning, I received an email saying " Your account incurred a House Call for trade date 01/07/2021 in the amount of $1,183.83. That might explain the restriction BUT by that time I have already liquidated positions worth way more than the required amount. So now I should be in the clear, but the restriction still holds, more than one hour after the requirement was satisfied. The question is, how long will it hold?
