Got the same problem as the OP describes, this solved it for me:
-From your site dashboard go to Jetpack configuration and take note of the username it shows you are connected as.
-Disconnect your account.
-!Backup of your database!
-Go to your database and search for the username you copied. It will show up in the “options” table.
-Delete the entry.
-Go to your dashboard and connect Jetpack with the desired account.
Apparently, when you disconnect your account, Jetpack doesn’t delete the option “_transient_jetpack_connected_user_data_1” from the database and when you connect it to a different account, Jetpack doesn’t update this entry neither.
Cheers.
