Keep in mind:
ROAS goal works best when your ad set gets at least 50-100 weekly conversions, which gives the system enough data to optimize delivery efficiently.
If below this threshold, consider broadening your audience, increasing your budget, or raising your cost per result goal.
The more conversions a campaign has, the more accurate the ROAS goal results you can expect.
Your actual weekly average ROAS may vary from your set goal.
Note: To use ROAS goal you must have a functional Meta Pixel or Meta SDK set up to track conversions events, and meet the eligibility requirements for the Maximize ROAS (return on ad spend) performance goal.
似乎是周转化50100？可能你这个像素近期数据不足
以及“must have a functional Meta Pixel or Meta SDK”，你这个像素是多老的，老到像素和数据集还没合并的时候吗？可能太老了 设置和他现在的要求不一样
