iPhone recurring prompt to install unverified profile

One of the users I support is receiving a prompt to install an unverified profile (InCommon RSA Server CA) on her iPhone several times a day. We have tried many things including network reset, installing the profile, review background refresh, check open sites in Safari .etc but the popups persist. Anyone seen anything like this? It's a personal device not managed by our MDM system. Apple support was consulted and they recommended the network reset but that was not the fix.

iPhone XR, iOS 18

It might not just be Safari or a web browser. Many apps these days are little more than front ends for websites and so any one of them might need a certificate. Email is also a likely candidate. Has the user got apps that give them access to company, university or school accounts or services?

I checked the iOS 18 Apple installed certs and it's not in the list, so it probably isn't the OS.

Thanks for your reply. You are right, I reviewed and the prompt is for a certificate that isn't installed. We don't see anything in her "Certificate Trust Settings". Something appears to be triggering a connection but I can't find it. Checked Background App Refresh, looked for Web Clips on her home screen, open pages in Safari that point to the web server referenced in the screenshots for the certificate. Thanks for any thoughts.

Are you sure it's a profile? It looks more like a certificate.
