Thanks for the reply. Seeking Alpha should communicate with Apple and find out what the problem is. It did just start a few days ago. I'm not big on having a lot of email accounts, so don't want to switch. Also, suspect that there are a lot of subscribers having this issue. Seeking Alpha and Apple should be able to sort this out.
Yes, I am pretty sure there are many users that are using Apple email clients. I did not receive any emails from SA since late last week and found it strange and thought my email client was having a problem. After I checked my account, I noticed the warning that my email client was rejecting the mails from SA but it seems the issue initiated from the new UI of SA. Other than the non-recent of emails, some users cannot close their account or change their email. Hopefully, SA will get the message and find a solution. In the meantime, I am going directly to SA web site and reading the notifications. Not easy but can live with it for the time being.
Ditto Exact same problem here.
