@Frustrated427 and @Caitlyn_Ring thanks for your suggestions. The thing is that I have a separate account that is only used for Ring. I have not linked it to amazon services and i do not own any other Amazon products. As far as i know, sidewalk works only with Amazon services.
Just to check somethings I have followed the steps in the manual https://support.ring.com/hc/en-us/articles/360032524592-Opting-In-and-Out-of-Amazon-Sidewalk The option “Sidewalk” that is mentioned in the manual, is not available in my ring-app (have the latest version).
I have called the customer service off Ring before I posted this message. The response I got with the cause was not really satisfying. I was told that it had something to do with an update to the system with Ring and that it shouldn’t happen again. Because it’s not the fist time I see this kind of messages, I have no faith that it will not happen again.
And two new messages that i see now confirms my faith that I didn’t have in the answer.
I call again the customer service, this time I demand further investigation to the real cause of the messages. There must be a reason I keep getting these messages.
Long story short; it has been forwarded internally for further investigation. I’ll keep you posted when I know more about this.
