Autofill No Longer Working Xcode Developer or TestFlight Signed Builds?

Thanks for running that, sixbillships.

It looks like the problem here is that its just an "adhoc" code signature with no trust chained back to Apple. Ad-hoc signatures have no cryptographic proof to back up their validity and generally don't support as much as normal signatures.

I'm not sure there's anything else to do right now about this, so you have my apologies for the inconvenience this is causing. We will consider this use case and see if there's a good way to support it without compromising on the security of Universal Autofill in other cases, but I can't make any promises.

Thanks again
