Reminders initial setup is showing a yellow triangle & does not work

Hello, I am new to em Client and may have made an error in setting up from iCloud. I have got all my emails working and have all my Calendars working from iCloud, but on the same account it will not download any tasks from my Apple Reminders folder and in the account section it is coming up with my name and none of the (6) tasks sections that I have, just a yellow triangle.

Any ideas how to solve, please?

Thank you in advance.

Is this of any help:

Upgrading the Reminders app in iOS 13 or later - Apple Support

Hi Gary,

Thank you, but it does not help. My Calendar is all working but I cannot get reminders to sync.
