Hello, I would like get advice about the time-sensitive notification ‘interruption-level’ set to ‘time-sensitive’ in the push payload. I’m wondering if this setting applies to VOIP push notifications. I tried to find information in Apple’s documentation, but it doesn’t specify whether it is applicable for VOIP push notifications. { "aps": { "interruption-level": "time-sensitive" } } https://developer.apple.com/documentation/usernotifications/generating-a-remote-notification#:~:text=ContentIdentifier%[…]terruption%2Dlevel,-String

Some users couldn't receive push notifications, and APNS returned a 'DeviceTokenNotForTopic' error. Upon validation using Apple's tool, I found that some tokens are identified as VoIP push tokens, and some as Live Activity (LA) push tokens. When attempting to send a normal alert push using these VoIP/LA push tokens, it didn't work and returned a 'DeviceTokenNotForTopic' error. These tokens were obtained from Apple's delegate function 'didRegisterForRemoteNotificationsWithDeviceToken.' It's unexpected to receive VoIP/LA push tokens from this event, but this issue is occurring, and I've observed it specifically in iOS 17 users. This problem is not universal and is happening only for some users. Please take note that our app support VoIP Push, Live Activity Push and Normal Push notification. Could this be an iOS 17 bug? Any advice on this matter would be appreciated. Thanks.
