Why can't we see weather radar in mainland China now? Is it a bug or is it intended to block mainland China?

@Nicole-Dolezalova Thank you so much for your reply, I am so relieved to have you guys answering like this, we love this app at home, it's great to be able to prepare for a trip and effectively observe the current weather! Hopefully it will be fixed soon.
