Now this is live is there any tech guides on how this is implemented? Specifically around the identifications, is there any links back to the original purchase ID at all?

We are also seeing this, only iOS15 devices are causing this

Yes still seeing this on a decent number of 15.2 devices too

Yes I am also seeing this now with the 13.3 release. We also cannot disable BitCode due to a WatchOS app

Disabling Bitcode sadly is not a fix if you have a WatchOS app

So far I have not seen any 15.4 crashes for this

Didn’t they deprecate this method for APNS? Now token based
