I am unable to replicate any issues with the takeoff speed export on my side. After calculating the takeoff performance on the EFB Performance Calculator app and pressing the "EXPORT TO SPEEDS" button, the speeds are being exported into the FMS and displayed on the PFD as expected.
It may be worth noting that any changes to the weights entered in the FMS will invalidate the takeoff speeds, and they must be reentered (for example, if the "EXPORT TO SPEEDS" button was pressed followed by the "EXPORT WEIGHTS" button, that would invalidate the takeoff speeds and they would need to be reentered).
I believe the speeds are also invalidated if the departure runway or SID is changed.
Hope that helps.
