Additional Information:

@Mattches Have you been able to see some of what’s been going on that’s causing these message to pop up on various OS yet?

@jsecretan I know I sent email of a couple others, but since you said wanted tagged, here’s a new one showing the issue here on MacOS. Otherwise I’d just strictly have tagged Mattches, but guess including both for the moment.

Please see the following post for information on how to resolve this issue:

Hallo Mattches,

thank you for you feed back.

I have changed the setting of Keychain Access App in macOS (please see screenshot below) and additionally reset and re-sync my devices.
I am happy, because now it works.

Thank you very much for you quick and effective help!
