Account is not authorized to trade in live account

Hi Guys,
My account just got approved and was able to deposit funds successfully.
When I tried to use API to trade QQQ using my live account, it complains “Alpaca: order for symbol SQQQ is rejected account is not authorized to trade”.

I tried to send an email to to ask for help, but Gmail complains “this email address not found”.

How can I get help to fix the issue?

Thank you!

Hi Apple there’s a typo in the email address
