Serial (Player Only)

Does anyone recall if there was some configuration command required to get the “Serial (Player Only)” option to appear in the list for the Run Device Function trigger action? I am in LTS 8.2 (still…) and we have this option in our DEV instance but it is not present in QA (or PROD) so our connection steps are not working for UAT.

Update: one of our IT folks found the feature flag for this:

Once enabled, without any trigger edits, the “Serial (Player Only)” selection was automatically restored, and the app functionality was restored.
