@ml1344677 我的还是不行，有个请求浏览器控制台有报错 ，搞不清楚什么原因 password?state=hKFo2SBLbG5ERXlobmEwSnFPQ2hXM0dPcnU0aEM5XzBSU3dobKFur3VuaXZlcnNhbC1sb2dpbqN0aWTZIEZ5aTdrUkhaSm9GdFYzRDJTQnNsZ25OTXZ4c0U2TFM3o2NpZNkgVGRKSWNiZTE2V29USHROOTVueXl3aDVFNHlPbzZJdEc:642 GET https://chatgpt.com/backend-api/sentinel/sdk.js net::ERR_BLOCKED_BY_RESPONSE.NotSameOrigin 403

@ml1344677 是的，登录按钮无法点击。我一般用无痕模式，之前登录的窗口发不了消息

@AiBoy 怎么处理的？被这个问题困扰好多天了

同搬瓦工，会话一次就要刷新一次

@zw1234 求拉 base64 Y2hpbGx3aW5kdGFu

@vone 应该不是，切换完其他 app 这个悬浮窗应该会消失。而且没有给 SYSTEM_ALERT_WINDOW 权限

看了半天 swift，自己人肉转了一个。用的不对的地方，还请各位指正

@DeweyReed 今天试了一下 paging + room，通过 onZeroItemsLoaded 初始化数据，onItemAtEndLoaded 拉取后面的数据，测试基本功能可用，但是 onItemAtFrontLoaded 数据会有问题，onItemAtFrontLoaded 开始就会执行，而且 RecyclerView 定位到 onItemAtFrontLoaded 的第一条数据，而不是 onZeroItemsLoaded 的第一条数据。不知道是不是我对 PagedList.BoundaryCallback 理解不对，还是有别的方法？

@DeweyReed 用 paging 刷新时也会卡一下的，感觉是靠 SCROLL_STATE_IDLE 触发的加载数据，没有 onScrolled 里做的加载顺滑
