### 1/5 — 明明免费app确自动扣费，还自动帮你确认协议

*2019-06-04*

垃圾软件，早上下载的，就选择了无线网局域网选项还有允许访问地址，中午居然收到app自动扣费信息。大家不要下载了。不给我显示评论我就天天刷

**Developer response:** 不知道产生了什么误会，苹果的系统是不可能做到app自动确认扣费协议的呢。而且本app根本没有收费功能，有收费功能的话在appstore的信息页面都可以看的到哦

### 4/5 — 提点意见

*2017-05-25*

可不可以吧色块放大点！铺面下半个屏幕最好！

**Developer response:** 现在点击色块就可以全屏展示了哟。不知道这样能否满足您的需要？
