Yeah, had the same thing happen. One setup gets killed quick, then same funnel with a different cloaker holds much longer. Makes you realize how much the cloaker matters. Tried a few cloakers like jci, trafficshield, adspect, noip etc. some are good but too expensive to use, some are not good and some are best at a reasonable price, so choose wisely. Changing creatives or slowing spend helps a bit, but if the cloaker isn’t solid, it still trips the filters. Seen better results when the setup's tight from the start.
