It seems fixed for me as well, like @ElScruffed reported.

I just logged into the game and now the minecarts work again, they do not stop for no apparent reason anymore.

So strange. I guess Mojang fixed something ... could it have something to do with the Realm problems the last few days (I play on a realm)?

@ElScruffed Really? I gotta check my farms when I get home then. Hopefully mine are fixed as well then...

I have the same problems since updating to 1.21.21.

Most of my minecart collection systems just do not work anymore.

The minecarts stops for no apparent reason, just like shown in DisasterCheof17s vidos (see above). 

I have no idea why some of my collection system works but others are just completly broken.

This is pure speculation but it seem like the minecarts stop when there is a hopper under the track.

It also seem to have trouble when the track is just back and forth.... I seem to get more success when I build the track as a circle.
