Yealink 28.82.0.20

[engine411]

Also waiting for 3CX and/or Yealink to give a resolution here. Same issue as the OP. I had to manually downgrade all my phones to 28.81.0.110 so that shared park works.

In the phone when it's upgraded to 28.82.0.20, first, I can't get shared park to work in the phone's web gui, and second, the tooltips at 'Features > Pickup & Park > Call Park' are useless. Often you can use the tooltips as a clue to find the proper configuration parameter to change in the template, but here, the tooltips are useless.
