Edward,
Thanks so much for the detailed reply. The C/S people at NYT worked with me for over 2 months to fix the problem. I had a subscription for years that just stopped working for the newsletters. In the end, I had to re-assign my subscription to a different email. Fortunately, my husband and our businesses have more than one web host so we switched it. Not everyone could do that, it was a pain, and I still think they should have been able to fix it from their end ... but I was worn down after months and just wanted to get back to normal. So glad it worked, finally. Still kind of holding my breath every day though! :)
Again, thanks so much for your thoughtful response.
