Did you try our guide here: https://www.davx5.com/tested-with Do you use the app-specific password?

[Synchro iCloud]

Hi,
I don’t use the app-specific password.
I must generate it and for this, I must activate the two-step authentication (I can’t activate two-factor authentication because don’t have an iPhone anymore).
And to be able to activate the two-step authentication, I must wait a few days (April 2), it’s imposed by Apple.
I will test and come back to you to communicate the result.
Regards.

Apple doesn’t allow synchronization without app-specific password, so yes, please tell us about your results.

Hi,
Now, all is well.

I used 2 free applications that I deleted because the automatic synchronization no longer worked.
With DAVx5, everything works perfectly.
It’s user friendly and very simple to use.
Thanks.
