After the update to v. 1.21.130 (Bedrock Edition), all tamed horses (in all my Minecraft worlds) now have the same sluggish ‘riding parameters’ as skeleton horses do. Same sluggishness, same ‘delayed jumping behavior’.
I really hope, this is a bug, and not a ‘new horse feature’, because with that, horses become impractical to use!
