So I've got multiple apps on the App Store, one is very complex and another that is more basic. The one that is more basic continually seems to be skipped over in the review process and just sits there in waiting for review (currently been there waiting for a week), while the other gets reviewed within 24 hours. I'm grateful the more complex one clears quickly as I am making several updates each week, but I need the other to clear in a timely manner as well. This is not the first time with this particular app and starting to wonder if there is some issue with the intended audience. I sincerely hope that is not the case. Thank you App Review folks, I know you're swamped, but can you please look into this seemingly repeating issue and let me know why the hold up on this one app I'm particular?

I would like to start up by saying how much I appreciate all the Apple employees, developers, reviewers, and testers for the incredible job they do. The number of apps that come through on a daily basis is probably astronomical. All that said, I am a bit curious as to why I was able to put three different apps into review in the last 24 hours, and as of now, they have all 3 been processed and released. In the meantime, I have an app that is still in Waiting for Review. This app has some core functionality involved as well as some more simple text changes. I’d to hear from Apple at the least, what is the hold up. If there is a code issue, tell me. If there is a behavior or UI issue, tell me. One of these changes was time critical for releasing in June. Thanks for letting me vent. I just hope the App Review folks look into it.

I am working on an app built in Swift and UIKit that uses audio playback over bluetooth. I am finding different amounts of latency for different devices, and it seems consistent across a given make/model. For instance, using an iPhone XR as the source, Bose On-Ear lags at 0.45 secs, Sony Pros lag at 0.3 secs and AirPods Pro lat at under 0.1 secs. I'd like to adjust latency based on collected data for "known" devices, but need a way (w/out asking the user for input) to detect the make and model of their bluetooth audio device Is this possible to do, maybe using core Bluetooth, or not?

Is it possible to predict gender and/or age using voice input within an app from an iOS device? We are working on a vocal singing app that needs some level of gender and age recognition in order to attempt to improve the user experience and to better provide suggestions of songs to sing. Does anyone know if there is an Apple SDK or 3rd party SDK (Git Repo or otherwise) that can take a voice sample and attempt to predict the gender and/or age of the speaker? Preference is to make it all on-device to allow off-line use as well as to protect the users information. We have a dedicated secure server that could be available if on-device is not an option. We do already have a voice interpreter for key phrases, but the gender portion is (understandably) more of a challenge for a variety of reasons. As always, thank you in advance to the great community of folks who help each other on this platform.
