Cannot join server after turning on 'use cellular data'

I joined a server on minecraft 1.16.20. When i want to log in today, i got an error 'outdated client'. I fugured out i need to update my minecraft to 1.16.100. after updated, i go to setting > profile. I turn on use cellular data. When i go to play > server > server i am playing, i clicked join. It said 'you need to connected ti Wifi to play'.  But i already turn on use cellular data.
