On our website, we are selling a physical product. The product works with an App. When you download the app you are asked to enter your order number to be able to fully use the app. If you do not have an order number, you can click on an "order now" button, and you are redirected to our store to order the product. Is this conform to the apple guideline or is it mandatory to allow the user to buy the product directly from the app?

We are a small Startup and we tried to publish our app a few days ago on the AppStore. In our app, the user selects an image and this one is processed on the cloud, the process is AI-based and took long time, about 15 minutes. The user is requested to leave the app and a push notification is sent when the process is finished. The app was rejected because of this waiting and we were requested to keep the processing time smaller than 5 minutes as mentioned in the guideline (we never found this mentioned in the guideline). We did our best to reduce the time but the App was rejected 3 times for the same reason. On the fourth try, we received this Email We need additional time to evaluate your submission and Apple Developer Program account. Your submission status will appear as "Rejected" in App Store Connect while we investigate. However, we do not require a revised binary or additional information from you at this time. We did some research and we were shocked to see that many people did not receive any information weeks, and oft months, after having received this message. How is your experience with that? We managed to reduce the time to one minute. We also fixed a few other bugs in the app and we think that we are now completely conforming to the guideline. Do you think it makes sense to submit the same app with another account or will this result in more problems with apple?

After submitting our first, a very simple App, we got a message from Apple We need additional time to evaluate your submission and Apple Developer Program account. Your submission status will appear as "Rejected" in App Store Connect while we investigate. However, we do not require a revised binary or additional information from you at this time. One month has passed and we are still waiting. We tried to contact Apple, filed an appeal ... Nothing helped us. Our company is dying because of this. Any idea on how we can solve that? The last message we received Thank you for contacting App Store Review regarding the review of your app, “***.” I understand your concern regarding the extended review time of your app. However, we still need additional time for review due to high submission volume. I escalated your request to the appropriate internal team, but we can't provide an estimated completion time. When the review is completed, we'll notify you about any next steps in the App Review section in App Store Connect. In the meantime we worked on the App and we made major changes. Will it help to delete the submission ans make a new one?
