Several times happened to me that after some actions like Measure / Free measure / Select / ... the different lines remained displayed on the screen and I could not make them dissapear. Please let me know how quickly clean the screen so only recorded objects remain visible.
Tap and hold the stylus on the screen and select 'Restart'.
Restart: Erases all vertices and editing lines (construction lines) from the map view. Cancels changes to an existing feature’s geometry or cancels capture of a new feature.
