Account on hold

Small query. Opening my account I had to provide copies of ID. Account was approved. After depositing funds for the second time, I have been asked for proof (of address). Until verified, account is now on hold. Is this standard?

I believe this is common practice, nothing personal.

@Vorny Here you have the answer:

Nonetheless, I can see that our team verified yesterday your POA document, so you’re all set now.
