Description

It seems that iOS and macOS 26 has a limit on `pirAuthenticationToken` which is not documented anywhere:
https://developer.apple.com/documentation/networkextension/neurlfiltermanager/setconfiguration(pirserverurl:pirprivacypassissuerurl:pirauthenticationtoken:controlproviderbundleidentifier:)

When I try to use a token that's longer than 8 characters, it just does not even attempt to contact the privacy pass service and obtain tokens from it.

Could you please confirm this behavior? Are there any other limitations?

Research direction

Start with the linked NEURLFilterManager setConfiguration documentation and reproduce the reported behavior on iOS or macOS 26 using a pirAuthenticationToken longer than 8 characters. Confirm whether the privacy pass service is contacted, investigate any other documented or observed token limits, and update the relevant example documentation with the verified behavior.
