Reminders issue iCloud

Hello, I am a user of your PRO license and I cannot sync reminders with my iCloud account. I always get a warning triangle next to my reminders see screen below.
The communication does not work in either direction (eM Client → iCloud; iCloud → eMClient).
The email and calendar connection works as it should, the only problem persists with reminders.

I would be very happy if this bug could be fixed.
Thank you in advance.

If you are getting a sync error, you should find the error listed in Menu > Operations > Log tab.

But you should be aware that if you are using Reminders on iOS 13 or later, iPadOS, macOS 10.15 Catalina, or watchOS 6 or later, Apple will no longer allow you to sync those items with non-Apple apps anyway. That is a restriction directly from Apple.

I will use iOS version 15. For me this feature is quite important as I use it daily and I would love to be able to use it through eMClient. Is it possible that this functionality will be restored??

That is something you will need to ask Apple.
