iOS 18 Bug -Certificate Trust Settings for Private Root Certificates Not Available

When can it be fixed? Can apple engineer help to escalate the issue? Thanks.

FINALLY I fixed it without resetting my iPad/iPhone, by using the Edit Backup file and restore, from the third-party Mac App you know.

1. Backup your device running iOS 18
2. Use Mac App to extract the backup files
3. Remove the MobileDeviceDomain, KeychainDomain, ProtectedDomain, 3 folders
4. Restore the edite backup to your device

Done. https://twitter.com/DreamingPiggy/status/1857459220091908594

@DTS Engineer - Hey Quinn,

I just upgraded from an iPhone 13 (which had my custom CA root installed and trusted) using Apple's upgrade path (backed everything up to iCloud, put the phones next to each other, and let them do their thing). The install did not include the root cert from the iPhone 13.

I am testing the waters before any of my users try this, and I am stuck. I am stymied by the lack of root cert trust settings in 18.1, which keeps OpenVPN from connecting to my private network. This completely breaks remote access, for me (and for any of my users that might upgrade to a new phone), as it hangs on verifying the OpenVPN server certificate.

Before I distribute (dangerously) altered OpenVPN profiles that do not try to verify the certificate, is there an ETA for a fix?? Thanks!

An update - I discovered that installing a certificate from HTTPS sites (vs. email, which I had been trying) works. OpenVPN accepts this certificate even though it is not trusted, which lets me work around the connecting from outside issue.

What this does not solve is every internal website or service using my custom CA's signed certificates shows up as untrusted. This is a pain, and I really hope it is fixed soon!

Slightly different angle. Installed 18.1.1 on a six month old iPad. After rebooting get a message about an untrusted certificate which expired in 2016 - related to an email no longer used email server. There does not seem to be an option to list and delete certificates. Nothing under VPN and Device Management.

we also have customers who told us about not working vpn‘s because of missing root ca‘s. watching this here very carefully and hope this will be fixed soon.

After upgrading to iOS 18.2 b4, I can finally see the missing certificates in the Certificate Trust Settings but there are certificates from previous backups and I’m unable to remove them.

Same. After updating an affected iOS 18.1 to iOS 18.2 beta 4,

• An unremovable certificate is listed in the Certificate Trust Settings. Even after removing all the profiles, it stays there.
• I can install root certificates and trust them.

Although the behavior is weird, it seems that we can now trust certificates without erasing All Content and Settings.

I submitted FB15921702 about previous reply on iOS 18.2 beta 4.

Yep. That gels with my expectations based on the resolution I see for the bug. Thanks for checking!

Yeah, that’s a different, but obviously related issue. And so…

Thanks!
