Cancel (template too old)
What it is
A button in the Save & Deploy pop-up that says This template is too old for the new login format.
What to enter
Nothing to enter. It is a button you press.
What it changes
It closes the pop-up. Nothing was saved or published. Nothing in the house changes. Nothing in the app changes.
If it goes wrong
The deploy will stop the same way until the app template is v2.64 or later.
