rielly

I've tried reeling in the fishing rod as soon as the fish particles reach the floater, and reeling in after when it is under water, and reeling in after it bobs back up. If it's a timing issue on my end I would say the time frame where i would catch something is too short. I've fished before i do know how it works.

It might be a unique problem, but i am responding to this thread because it most accurately describes my problem. So i assumed it hadn't been fixed yet.

I might try making a brand new world, without datapacks, optifine, or texturepacks but these things shouldn't affect fishing.

Resolution of this issue says "Fixed", However I just noticed i am having this exact problem in 1.16.4.
I'm not sure if it was fixed in earlier versions, and became an issue again in 1.16.4 or if it hasn't been fixed yet.
I am able to catch things like bows, enchanted books, and i'm not sure what else. But i am unable to catch fish, or any common drop as 95% of my catches result with nothing.
