Authentication Error when trying to connect my iCloud account to Spark macOS client.

Dear all,

I am having problems following the procedure indicated on the Spark documentation to connect the iCloud account to the Spark macOS client.

The steps I performed are the following:

1. Click "add account" on Spark and select "iCloud."
2. Open my AppleID (which mail has the gmail.com domain).
3. Generate the "App-specific password."
4. Go back to Spark: add my @icloud.com account and copy the just generated "App-specific password."

However, all I get is the error: "Unable to authenticate with the current session's credentials. Make sure to use the App-specific password."

What should I do? I tried different combinations, as:

• generate the password and then start the "add account" procedure in Spark
• generate the password and then restart Spark
• remove and regenerate the passwords on the fly

Nothing seems to work.

When I enter the AppleID "Personal Information," and I look at "Reachable at," my two mails (gmail and icloud) are both present.

I really do not understand what can be wrong.

Thank you in advance for your help!

Best,

Andrea
