You have chosen not to trust Digicert CA message
Hi,
2019 MacBook Pro running Big Sur 11.6
Trying to use Citrix Receiver to access a remote desktop.
I keep getting the message "You have chosen not to trust Digicert CA" with a big blue 'Quit' button.
I've gone into Keychain and changed all the Digicert certificates to 'always trust' but still the problem persists.
Searching Google hasn't helped so far.
Any ideas, please?
MacBook Pro 13″, macOS 11.6
