Getting a "certificate is not trusted" error for iOS Distribution Certificate

To support an older version of an iOS app, I needed to install Mojave with Xcode 9.

I create a CSR and from there generate an iOS Distribution certificate online, which I download and double click to install in Keychain. However, when viewing in Keychain, it shows in red "iPhone Distribution: CompanyName certificate is not trusted".

I'm not sure what I'm doing wrong as I follow the instructions to the T and have done this in the past with success.

NOTE: I tried this with Sierra as well and got the same issue. It only seems to work on Catalina, which doesn't help me because I need an older version of Xcode.

Hello Patel Bhai, How are you doing? I have registered brand new paid apple dev. account and I keep getting Revoke for each device. Revoke certificate

Your account already has a signing certificate for this machine but it is not present in your keychain. To create a new one, you must first revoke the existing certificate.

I opened trouble ticket to Apple three weeks and keep running me around without any help.

When I checked Keychain in Login and My Certificate is Valid and in Green color.

If anyone having this issues then please respond and help me.

Thank you kindly, Jason

I needed the G4 certificate from here. Maybe because it’s a year later from when the above solution was posted?

In any case this is pretty messy.
