为什么我买了PS年付费计划，却只有100个生成积分

@changmei_9830 that's right. If you subscribed to this plan on or after November 1, 2023, you are allocated 100 generative credits per month. https://helpx.adobe.com/creative-cloud/help/generative-credits-access-and-use.html

You can usually purchase additional generative credits or wait until they reset each month on your billing date.
