When editing a dashboard input button, nothing that I had previously entered bor the button showed in the payload field.
I had to click the “Trigger Workflow” option to show up.
After that it shows up even if I click “Send Device Command”
I see what you mean; when you first open the panel for the button editor, the input for the payload field appears blank. But if you interact with the field (click within it) the value you entered previously will appear.
Rest assured it’s just a display issue; your payload is still there. Thanks for the report, and we’ll try to get that fixed in our next release.
