Hey @Ruslan S  Ayk here from the Support Engineering team at Intercom

This error normally occurs when the bundle_id that you uploaded when setting up your push notifications is incorrect. I'd have a look at that and verify you're using the correct bundle_id.

That would be setup in Settings>Installation>iOS in your Intercom Workspace. You'll want to make sure the bundle ID matches the bundle ID of the app that you want push notifications sent to.

Apart from that, I also highly recommend checking our docs here to make sure you have followed each step.

Hope this helps!
