Why can't Le Rabbit read?

Because of some technical reasons, it will lead to some bugs, and then we see that these always need us to solve, so wait patiently.

In Tu Tu reading of APP, 1 may cause some bugs due to some technical reasons.

I also like reading novels. As far as I know, the certificate of rabbit reading has expired, so it can't be used now. I want to wait for a new certificate!

This depends on whether the APP official has re-certified. If he doesn't apply for a new certificate, then the software will remain like this and won't be used.
