Hi @Anonymous ,
Do you want to reset multiple Checkboxes when you navigate to the target screen (which contains the multiple Checkboxes)?
Based on the formula you provided, I think there is something issue with it. I have made a test on my side, please take a try with the following workaround:
Set the OnVisible property of the target screen to following:
UpdateContext({ClearCheckbox: false});
UpdateContext({ClearCheckbox: true})
Set the Reset property of each Checkbox control within your Target screen to following:
ClearCheckbox
Please consider take a try with above solution, then check if the issue is solved.
Best regards,
