Spend that does not pay back is not a creative problem until it has been a channel-economics problem.
Marketing 'not working' is almost always CAC, payback, or mix — a channel that used to pay no longer does, a channel that never paid is still being fed, or the offer converts and the unit economics still do not. Creative tests on a channel whose payback is already broken waste the budget that should move to a channel that still returns, or to retention. Pause is a decision; 'optimise the ads' is often a stall.
The move that usually makes it worse: Increasing spend on the channel that already missed payback, hoping volume will fix unit economics.
Percision is the wrong tool if you already know the answer and only need execution capacity, or if the business is pre-revenue — then the constraint is evidence about the market, not analysis of your own figures.

Strategy School lesson: which-channel-pays-back
If payback is already broken and the offer has not changed, more spend is how a CAC problem becomes a cash problem. Pause is cheaper than a creative refresh on a dead unit.
Sometimes. More often the channel economics are visible in cash even when the last-click report is noisy. Rank channels by payback with the numbers you trust, and be honest about the ones you do not.
