Segmented Switch widget: strange virtual pin behavior

After adding some Segmented Switch widgets to my project (Blynk App Android 2.27.0) virtual pins have strange behavior:

  1. Segmented Switch widgets are allowing use of any “used” virtual pin
  2. Segmented Switch messages (options changes) stopped triggering in the sketch (Arduino).
  3. Some virtual pins are marked as “used” while they don’t exist in the app. These “ghost” pins are not found in the project listing.

SOLVED - Mea Culpa.
Reason for this behavior came from having two different target devices in the same project. My Segmented Switch widgets were binded to a device whose token did not match with the token in the sketch.
Also, it is now clear to me that the project listing is only showing widgets whose target device tokens match with the token in API call.
