Errors in signing in account

xkgzgzkgzk on

Japan

Errors occur when signing in and the app automatically logs me out, over and over again. After trying to sign in, it logs me out immediately, and the classes do not load, all after the new update. I’ve always loved using the app version of Khan Academy, but it is currently unusable. Please fix this bug as soon as possible.

差评!

每次在一个单元里只剩二三十个掌握点时,我只要在单元测试里错一题,退出来之后就会发现,原本只剩下二三十个掌握点变成五六十个掌握点了!我的天,他真的让我发疯,所以我拜托订正之后能不能判他是对的,而不是判他是错的,可以吗?还有就是我做的题明明是对的,但是他告诉我是错的,然后查看答案一看,他弄错题了,原本这一道题的答案变成了另外一道题的答案,听懂了吗?就是他的题显示错了。差评!希望可以改进。

It’s good but like it’s not fun.

日本語に対応してほしいです I would like it to support Japanese.

とても使いやすく、数学がわかりやすいです! 不便があるとすれば、日本語に対応していないところです。だから、日本語に対応してほしいです! そうすれば私たち日本人ユーザーも使いやすいと思います。 Very easy to use and easy to understand mathematics. If there is any inconvenience, it is that it does not support Japanese. Therefore, I would like it to support Japanese!! I think that would make it easier for us Japanese users to use.

完美的教育!!!
