Adding some notes as I work through this while waiting for Apple response: Request for Apple: Please make yellow status indicators clickable. I feel like I should be able to click "Missing Metadata" and have a pop-up show me specifically what metadata is missing. Notes for others who find this while trying to solve similar/same problem: It is possible for this to be broken even if you passed sandbox testing and Apple has approved your app for release. Highly recommend verifying in actual AppStore that in-app purchases display - especially before starting an ad campaign. On the AppStoreConnect pages to set up subscription groups and individual subscriptions, treat every field as required - unless the field explicitly calls it out as optional. In my case - the status didn't change from missing metadata until I added localizations and Review Information Screenshot. Review Information Screenshot - Size requirements: Image will not upload unless it adheres to the sizing constraints found here. Sizing constraints found here - Apple Documentation in AppStoreConnect > Apps > Distribution > iOS App > {version you are releasing} - If you do not see your subscriptions under In-App Purchases and Subscriptions on this page - then your subscription/in-app purchase is not a part of your submission - and it will not show up in the AppStore. I was previously under the belief that I only needed to set up subscriptions on the page under Monetization from the left side menu bar. This thread from the forum helped me a lot and contains more information about other things that need to be checked if it still isn't working for you.

Just wanted to add a final addendum for anyone who finds this thread in the future. In my first addendum I said to make sure your subscription shows up here: in AppStoreConnect > Apps > Distribution > iOS App > {version you are releasing} - If you do not see your subscriptions under In-App Purchases and Subscriptions on this page - then your subscription/in-app purchase is not a part of your submission I still think this is accurate; however I do want to call out that it was visible for me to view as part of my submission prior to submitting. When I went back and looked at it after the submission was approved - it was no longer there. I panicked a little thinking that I had a live App Store listing without subscriptions again - but when I checked the app listing, it did show in-app purchases. More importantly, when I downloaded the app from the App Store and tested the onboarding - the paywall showed the subscriptions correctly and allowed them to be selected. The second thing I want to call out is that after going through and submitting with all the information that I called out in my previous post, my re-submission was rejected. The rejection notice wanted me to list links for Terms of Use and Privacy Policy. Here is how I fixed and got it to pass. (Privacy Policy) From the left-side menu bar in App Store Connect, I selected App Privacy and made sure that the link at the top was working and accurate. (Terms and Conditions - EULA) This was hard for me to find. From the left-side menu bar in App Store Connect select App Information. In the middle of the page - there is a small heading that says "License Agreement". I'm using a custom EULA - so I clicked Edit. I then copied and pasted my full Terms and Conditions from my website into the field for Custom License Agreement. After doing this, I pasted both links to these documents and my website in the into the optional review notes field of the subscription, right next to the Review Information screenshot (which is required). Out of an abundance of caution - because I was desperate for this to be approved, I also pasted both of these links to the bottom of the app description which people see when they view the app description in the App Store. Finally, I created a screen recording where the first thing I showed was the rejection notice with the reason for rejections. Then, one by one, I showed where in App Store Connect I had added the information related to each bullet point of the rejection. I then replied to the rejection with a link to the video of the screen recording and resubmitted the app. After doing all of this - within six hours, the app was reviewed and approved for release. I had applied for an expedited review, so I'm not sure if this sped things up or not.
