found reproducing other issues: 1. In the APNs cron, the logger wasn't good enough to print an slice and the log message was "unsupported type" 2. `APNSDeliveryError` _always_ had `Err` set to nil, while we were catching those errors, it was impossible to see the cause in the logs (always printed err=nil) # Checklist for submitter If some of the following don't apply, delete the relevant line. <!-- Note that API documentation changes are now addressed by the product design team. --> - [x] Changes file added for user-visible changes in `changes/`, `orbit/changes/` or `ee/fleetd-chrome/changes`.
