Mac OS v10.12.6 - Mail v10.3 - I updated GPG 2 weeks ago. Since then I’ve had a lot of problems. I wasn’t able to open some encrypted emails; it just scrolls and scrolls Loading. I re-imported people’s keys & had them re-import my key; I was able to open their encrypted emails for a few days. Now the problem is back. Our IT Manager uninstalled and re-installed GPG today on my laptop; same problem - and now there’s an additional problem that some unencrypted emails from these folks also won’t open, and just scroll and scroll Loading. We tried uninstalling & then only installing the non-GPG Mail components. Then I can at least open the unencrypted emails…but as soon as we added GPG Mail back, same issue - I can’t open either encrypted or unencrypted emails from folks in my GPG Keychain.
