Chinese input is not working after upgrading to Catalina (10.15) in MacBook Air

I tried the im of baidu (百度) and sougou (搜狗), they are not working in any case. Because they need update acoording to the system hint, when I try to start other similar app.

I asked this question because there is no system hint when an im is not working in this case.

Now it is solved, thanks for your reply.

It is solved by installing a new version of input app.

For example, baidu input: https://srf.baidu.com/input/mac.html

Yes, I am just talking about 3rd party IM's, not Apple's. Apple's IM's is OK, but I have not used.
