My ACCA Membership Application is on Hold due to PER Audit

I applied last week for ACCA Membership and I just received an email from ACCA that Your application for membership has been randomly selected for a practical experience audit. This review will take place as quickly as possible and ACCA will be in touch to advise if any further information is needed from you to validate your membership application.

Have anyone had the similar experience and what kind of audit would it be? Can anyone please advice? thanks
