Open should work, close has been purposely disabled, at least for the phone app, part of the "solution" to the window pinch issue. Pinch had two aspects: 1. Closing force above NHTSA spec, before it would start to reopen; 2. How far it would reopen if a blockage was detected was too small to meet the NHTSA spec.
IF Lincoln actually fixed both the closing force and the reopening width, there is no reason they couldn't still offer remote close to work (both keyfob and phone app). Removing global close is a "patch", a hack fix.
