对所有评论YouTube API textDisplay为空

我们有一个网站一直在使用YouTube API为视频加载评论几个月没有问题。本周末，我们注意到，所有视频中的评论文字都已消失！作者信息，publishdAt等都通过很好，但snippet.textDisplay是空白的每一个评论。如果我在YouTube.com上观看该视频，则评论无误。对所有评论YouTube API textDisplay为空

有几个bug报告，似乎符合这个问题（和时间）。例如，＃7969 https://code.google.com/p/gdata-issues/issues/detail?id=7969。解决方法似乎是将textFormat用作plainText，但这显然不理想！ – theduck

谢谢，theduck！ –
