We’ve been there many times. Their platform support team isn’t very large and if they have people on vacation or OOO, their response time can be really slow. Just be patient with it. In the old days they might have just ignored you but they’re improved things at least to the point that they will respond, it just might take some time.
It’s also possible that they’re doing an in-depth review of your application, which can take time.
As a piece of advice, I’d double check all of the rules and all of your application’s features and code for anything that could potentially be an issue. Preemptively making changes that you think might be the issue tend to move things along faster and it shows good faith on your part. If they’re slow to respond, the last thing you’ll want is a bunch of back and forth before your restriction gets lifted.
