14-16 weeks is the aimed for optimal timeline. Depending on the number of verification teams, overall load each team has and staffing during holidays/pandemic issues, etc, it can easily run longer. And that's if most rides are just standard rides that are clear and easy to verify. Getting bogged down with difficult to verify rides can slow a team down. Waiting for a specific answer from Mike or a response from a business about a receipt can easily add time too.
IMHO, give it to the 6 month point and if you still haven't heard anything, yes, it's time to investigate more and try PMing Ira, (or Howard Entman on premier submissions).
