I added some siri default intents and noticed that they tend to call the system's default apps rather than my app instead. By adding "in my app name" to the end of the invocation phrase it seems to work (at least sometimes. But it still is quite unpredicable and siri often confuses "in my app name" with the content of the invocation. I have two questions that hopefully can be answered by someone more experienced with siri than me: 1) is this "normal" behaviour or are there techniques to improve this? Like setting a default app for handling an intent or such? 2) is it always required to add the "in my app name" phrase? 3) will siri get used to it by time? The current performance is not even close to anything I would like to have a customer to deal with :/ Maybe that also has an impact, I'm currently testing in german. When testing in english it feels slightly better. Thanks for any helful hint / direction!

According to https://developer.apple.com/documentation/appstorereceipts/status the status code 21007 is returned, if a receipt send to the production environment comes from the test environment. Therefore the recomended logic is as follows: send the receipt to the production endpoint if the response is a 21007 code, then send it to the sandbox endpoint But what if the sandbox also returns with a 21007 code? That's happening for me and I don't know how to resolve this. From the documentation side, this state is undefined. Does anybody know 1) what does it mean to receive a 21007 code when sending a receipt to the sandbox endpoint 2) how to resolve this? As you can imagine, following the above logic this results in a wonderful endless loop ;) Thanks for any help!
