I have a button that becomes visible based on a condition. Sometimes when the condition is true, the button does not appear, but the hyperlink where the button should be is active.
In other words, when the condition is true, the button is not visible, but if the user clicks where the button should be, the workflow is triggered.
I tried to check it out but the visibility of the element “Group Data Entry”, which contains the button depends of your database records, which I can’t edit.
Anyway, I reproduced your setup in my app (with old and new responsive engine) and I didn’t have this issue. Everything worked well.
I advise you to delete and recreate this button to see if the problem disappears. If not, I suggest you to fill a bug report.
And remember to change your App back to “Private App”.
delete the button and create a new one, I already had it with popup. This is the quickest thing to do than thinking about the cause, it could be a browser, it could be some condition that you don’t know where you entered. Better to redo, that’s good learn twice. Good luck.
