Hello, I don’t know if it is exactly same problem, but my wife has similar issue with her site martja.cz. Site somehow got duplicated on WordPress.com (www.martja.cz is seen two times in “My Sites”). Old (disfunctional) one always says “Jetpack 3.3 is required”, but she already has latest Jetpack 3.5.2 installed. I have even tried to disconnect and then reconnect again to WordPress.com, but that disfunctional duplicate in My Sites doesn’t disappear. Can you please help and get rid of this duplicate? My wifes account is martjasgcz. Thanks
