I figured out why Yahoo has not fixed my calendar and notes! It is on a ymail.com account and appears to be old like Classic mail and will not be supported just like Yahoo not telling us that the New mail is out dated and also is not being supported.
It’s been well over now four months and Yahoo still has not fixed my Calendar or Notepad so when is Yahoo going to fix the following?!?!?!?!?!?
On 5/23/2019 after Yahoo took away my email CLASSIC for this new and unimproved new format email my Calendar would not load because of an error. After further investigation found that the Notepad has the same error. What I get is;

“We're experiencing some technical difficulties...
We’re sorry, but Yahoo Mail can't load due to a temporary error. You can try back again shortly, or visit our help pages for ways to troubleshoot the issue.
• Try again
• Visit Help for troubleshooting instructions
Temporary error: 500”

I clicked on “Try again” and “Visit Help for troubleshooting instructions” and end up each going to the “We're experiencing some technical difficulties...” page again and again and again. What is Yahoo’s definition of Temporary error? Well it’s not a day so is it a week a month a year!

Give me back the CLASSIC email or I’ll send this every day until I find a new email service that fits my needs as this new email format doesn’t or I don’t have internet access.
