Hello,
I am having the same issue and have tried to contact Jetpack support AND began my own support thread multiple times however; I have yet to receive any assistance over the past two weeks.
My page is linking Tubmlr and Facebook to the temporary url that was used when I first set up my site, over a month ago. The subscriptions widget is also linking the wrong url to emails when someone tries to sign up to my blog https://hiphopflu.com.
Everything is up-to-date in settings/general and I have tried unplugging then re-plugging Jetpack yet, the problem still persists.
Please help.
