Changing the username makes the application unusable

Hey guys,

i have a Crazy issue since today.
When I open gitpoint, I see the cached news feed.
When gitpoint tries to update the news feed I only see a white screen and I can’t click anything anymore.

I‘ll add a screenshot on Monday, still have not internet at home.

Somehow I think my device is broken, have so many issues 😳

未指定文件、测试或入口点。首先在移动应用中更改用户名后，复现 cached-news-feed 更新，然后跟踪更新路径，并比较账户更改前后的行为。当 feed 刷新不再产生白屏或禁用交互时，即表示完成。
