Object Manipulation and Instant preview not working together

[knightcube]

SPECIFIC ISSUE ENCOUNTERED

I tried running the Object Manipulation sample scene (after applying fix given here) using instant preview but when I tap on the screen the andy game object does not get placed in the scene. It would be good to add this feature also. Here is the warning that is shown -

Instant Preview has limited support for touch based input

VERSIONS USED

• Unity: 2018.3.0f2
• ARCore SDK for Unity: v1.7.0
• Device manufacturer, model, and O/S: Nokia, 7 plus, Android
• ARCore: 1.7.190128066
  On Windows, use: adb shell pm dump com.google.ar.core | findstr /i "packages: versionName"
  On macOS, use: adb shell pm dump com.google.ar.core | egrep -i versionName\|packages:
• Output of adb shell getprop ro.build.fingerprint: Nokia/Onyx_00WW/B2N_sprout:9/PPR1.180610.011/00WW_3_39F:user/release-keys

STEPS TO REPRODUCE THE ISSUE

1. Run the Object Manipulation scene in Unity
2. Click on the play button to run in Instant Preview mode
3. Warning is shown

WORKAROUNDS (IF ANY)

Use Build and run after applying the fix here . Works perfectly fine. You can place the Andy Game Object and manipulate it in the scene without running into issues.
