Re: My account under review
Welcome to adwords community, In general account review is very normal for new accounts. This is because Google want to ensure account security, billing information, etc. Additionally ads, your accounts, and landing pages can be subject to review at any time.
Account reviews generally take 1-4 business days, however sometimes they can take a few time. If your account is under review for longer than that time-schedule, I would embolden you to get in touch with Google support team to contact at your specific account and bring it to the attention of Google review team.
