 * Hi [@titowhisky](https://wordpress.org/support/users/titowhisky/),
 * Thanks for reaching out. I’ll check this with the team and report back here. 
   I suspect this is an error that can be dismissed, as it’s related to a feature
   that allows Site Kit to show data from another site. If you can reproduce this
   error consistently and you’re aware of what causes it to appear, do let me know.
   I’ll also perform some checks on my side. Thank you.

 * Thanks for the update [@titowhisky](https://wordpress.org/support/users/titowhisky/).
   From testing the developer plugin and running some checks in areas where I suspect
   this error may appear, I didn’t encounter any such error.
 * If you happen to come across this one more, do let me know and we can investigate
   further. Thank you.
