Site stats lost after jetpack upgrade

I upgraded from jetpack 3.3 to jetpack 3.4.2 and all my stats have been deleted.

I searched the forum and found many unresolved and closed threads about it.

I tried the tricks with copying ids within mysql admin, which didn’t work.

I tried the trick with looking at https://dashboard.wordpress.com/wp-admin/index.php?page=stats&blog=MYID with passing my id, but this didn’t work either.

Is there any solution to this?
