A couple of weeks ago I upgraded the firmware of my Samsung UE65ES8005 TV (current version is 002007).
Unfortunately this lead to the "Samsung Apps" icon disappearing from the Smart Hub (see enclosed screen shot). I have tried everything to get it back, including updating firmware, resetting all setting to factory etc etc. When I click on the (now empty) place where the icon used to be positioned I get a box saying "Services Under Construction".
This is driving me crazy since I can no longer add new apps etc. Any ideas on how to get it back?
