Open a ticket with support. It will be forwarded to approvals. Shockingly the people in approvals only approve during regular business hours west coast USA time (GMT-8). Meaning holiday weekends like this (in the USA Monday is a holiday) can go about 3.5 days before you hear from them if you got diverted to manual approval early evening on Friday.
The “24 hours” in the email is just a blatant lie… It’s been this way for years, it’s more noticeable on a holiday weekend, but it actual over 24 anytime you get sent to manual approval after business hours on a Friday.
