Update: The app was approved on August 6.
In the end, I didn't need to take any additional steps, the review was completed and the app was approved.
The main takeaway from this experience is that, as frustrating as it is, patience is key. Waiting through a long review process can be difficult, especially when users are affected, but in my case the review eventually went through.
