Google OAuth2 身份验证问题：用户同意后网络浏览器无响应
Google OAuth2 authentication issue: no web browser response after user consent
问题
制作一个独立的（非网络）应用程序，它利用 Google Drive API 进行多平台数据同步。在 OAuth2 身份验证 (oauth2client.tools.run_flow) 期间，Web 浏览器有时在用户同意后不响应（= 问题）。 （出现这种情况时，刷新网页，授权返回没有问题，但我想用户可能只是觉得它被冻结了。）
Mac OS Catalina、Windows 10 和 iOS 14 会发生这种情况。
使用 Python 3.7.6 + Kivy。
详情
即使使用标准示例代码，我也可以重现我的问题（此处使用的代码只是对 Github 上的 Google Drive example 的轻微修改，来自 https://github.com/dtsvetkov1/Google-Drive-sync）。
在代码中，
credentials = tools.run_flow(flow, store, flags=None)
像这张照片一样在网络浏览器上打开用户同意屏幕
(press here for the image)
按下“允许”按钮，浏览器returns重定向到本地主机，应用在正常运行的情况下完成oauth2认证。但是，有时浏览器会一直等待、超时和身份验证失败。在超时之前，如果我刷新网页，浏览器 returns 重定向到本地主机，就像没有发生任何问题一样。
我按照说明 (https://medium.com/swlh/google-drive-api-with-python-part-i-set-up-credentials-1f729cb0372b) 启用 Google Drive API，设置 OAuth2 客户端 ID，在 Google 开发人员上创建 client_secret.json控制台并将 json 文件存储在当前文件夹中。
我也试过了
flow = OAuth2WebServerFlow(client_id=App.s.ClientID,
client_secret=ClientSecret,
scope=SCOPES,
redirect_uri="urn:ietf:wg:oauth:2.0:oob:auto"
)
但结果相同。
知道如何解决这个问题吗？

目前看来是浏览器问题。例如，
- 使用 Chrome 时，不会出现任何问题。
- 使用Safari时，会出现这样的问题。
- 从
开始，似乎“有时会成功”。
虽然我认为这个问题可能会在以后的更新中得到解决，但作为目前的回答，我认为这个问题取决于浏览器。
