So from what I'm understanding, iOS doesn't do periodic callbacks ? If that's true, does registering a new background fetch every time a background fetch is triggered work in the same way in practice ? If none of this is possible, then how do apps like RSS feeds readers regularly fetch data ? Thanks.

I'm testing an auto-renewed subscription in my app via TestFlight. The problem is that I can't find anywhere to cancel the subscription. If I go to Settings -> App Store -> Apple ID under "Sandbox account" -> Manage, it shows the subscription as Expired (since yesterday). However when I query verifyReceipt with exclude-old-transactions set to true, it still gives a status of 0, meaning the transaction is valid. Am I not verifying this correctly ?

I have had my Localization rejected (for unknown reasons, why is that not mentioned ?) and I went to change it. Unfortunately, I get an error when saving : "There was an error with editing your app store localization. Try again later." Great error. Looking at the actual json response from the backend, I'm getting this : { "errors" : [ { "id" : "597525fa-8873-47c8-a9b8-2efe62e5c049", "status" : "409", "code" : "ENTITY_ERROR.ATTRIBUTE.INVALID.UNMODIFIABLE", "title" : "The provided entity contains a field that can not be modified in the current state", "detail" : "The field (NAME) can not be modified", "source" : { "pointer" : "/data/attributes/NAME" } }, { "id" : "abad4d98-6553-44d7-90ed-adb6cf0196af", "status" : "409", "code" : "ENTITY_ERROR.ATTRIBUTE.INVALID.UNMODIFIABLE", "title" : "The provided entity contains a field that can not be modified in the current state", "detail" : "The field (LOCALE_CODE) can not be modified", "source" : { "pointer" : "/data/attributes/LOCALE_CODE" } } ] } So first off, it'd be great if Apple could actually show you the error in the UI, but moreover : How do I solve this ?
