I just downloaded Mailspring onto my desktop Mac Pro. I can’t set it up because I am getting an error message. It says the certificate is expired or invalid. I would greatly appreciate some help so I can get started with Mailspring. Screen shot of error message is included.
Can someone please help me! I continue to get this error about an expired certificate. I have been waiting 9 days and no change and no one is responding to my request for help.
