xamarin.forms ios 应用程序开始随机崩溃

Question

上次更新后，我们的应用开始在某些用户设备上随机崩溃。我无法在发布版本的 ipad 上遇到此崩溃，因此可能是特定于设备或特定于 ios 版本。 崩溃似乎与谷歌广告有关。

当我试图找到一个原因时，可能有人知道在哪里挖掘

提前致谢。以下来自 appcentre.ms 的信息。它来自应用程序主崩溃，但崩溃发生在不同的地方

好吧，原来我不是唯一一个 https://github.com/xamarin/Xamarin.Forms/issues/11183 似乎是列表视图中的错误。 降级到 Xamarin.Forms 版本 4.6.0.847 将解决此问题
