Can you post a link to a simple project that has this problem?

This is very simple sample : Can not click

Hi everyone!

I am also experiencing the same problem, I designed an app to read QR and register attendance it worked very well until the update V. 454-3 (April 16th approx) where suddenly instead of appearing the camera for scanning a blank screen appears and the button “cancel” as if you were reading the code.

I performed several procedures as advised in this community forums, but the problem has not been corrected. I tested it on the Thunkable Live Preview app and on the following devices:

  • Motorola One Vision - Android 10
  • Lenovo Tab10 - Android 7
  • Lanix Illium - Android Go 11

I also downloaded the apk to test on devices and got the same behavior.

I attach screenshots of the app, I appreciate any help because I was really liking the platform. I’m trying Kodular as an alternative, but the UI design is not as nice.


Ensure that you have gave Camera Permission to Thunkable Live test app.

All permission is allowed. I think it is a bugs (big) for Non-drag&drop users.

If the issue is still happening, then probably there is an issue with thunkable, you may Contact to Thunkable Staff

Same for me, all permissions granted. How we can contact to thunkable support?
