Appium 使用 automationName 框架为 uiautomator2 识别元素失败。切换 automationName 框架为 Appium 识别元素成功，求助！
问题：
使用 https://testerhome.com/topics/11720 的框架，通过 uiautomator2 识别元素，失败。
经过简单的查看日志，在页面更新后，需要刷新页面缓存才对，实际上切换 uiautomator2 框架没有这个操作。
操作
工程代码： https://github.com/leila-wu/pythonAppium 。执行 Runner 下的 runner.py，调用 HomeTest.py 执行用例。
日志与描述：
切换 desired_caps['automationName'] = 'Appium'。识别元素成功。 重点看到Failed to locate element. Clearing Accessibility cache and retrying.。取值失败，有清除缓存处理
该场景的其他元素获取正常，需要重新识别的元素，是页面小范围刷新。比如点击 A 按钮新增的 B 展示后，元素 B 获取失败
