When on a stretch of track, the Minecart with a player inside, slows down and speeds up seemingly randomly. Even if I try to speed it up the speed stays the same. I have only tried it on IOS 14.3 and unknown if other platforms are effected. Find the attached clip below (shortened due to size limit)

Is this still an issue in the latest version (1.17.10)? If so, can you please add it to the affected versions (or mention it if you are not the reporter).
This ticket will automatically reopen when you reply.

Unfortunately yes

Could not reproduce.
Can you provide a copy of the world affected?

Sorry for the late answer!
I think we can safely say that your issue is just another lag issue - going on to your world I noticed I had much less frames than usual. You have a lot of going on on that world, and there's no way your gameplay will be smooth on your iOS device if I had many performance issues with the world on PC. If you think this is not a duplicate, please create a new issue.
