Channeling Not Working

Having same problem on my windows 10 version. I have 2 channeling enchanted tridents and can not get lightning to strike even once! I am playing survival without cheats but tried on 4 or 5 rainy days and nights with no luck.

 ok so it is working now seems that you need more than rain... when its raining and you can hear thunder it works!!! But not with just the rain.

There must be a thunderstorm for channeling to work. This is probably WAI if it was just raining.
