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
