Honestly, half the time those "confusing" results come down to people chasing the wrong metrics. You're staring at ROAS like it's gospel, but if your attribution window's f*cked or your conversion tracking's got a leak, then yeah, nothing's going to line up.
I've seen this exact panic a dozen times. Someone posts a screenshot of wild CPC swings and a plummeting CTR, insisting the algorithm's broken. Nine times out of ten, they've changed landing pages, paused a top-performing campaign, or their competitor just launched a new ad set. Correlation doesn't equal causation, mate.
Check your cross-device conversions. Check your assisted conversions. And for the love of god, stop optimising on day three of a new campaign. The algorithm needs time to find its feet. You wouldn't judge a chef after they've just turned on the oven.
