IPad Pro 9.7, iOS 14.7.1. I don’t use any resource packs.
I am having this same issue with Caves and Cliffs on iOS. If I get out of a boat, as soon as I do so the boat disappears.
Happened to me so many times on an old trashy laptop. I was on 1.14.2.
I am having the same issue with the newest version of PE. I get coordinates using /locate, but they are not correct.
I am experiencing this issue as well, since 26.10. Playing Bedrock on Nintendo Switch 2, not able to access any worlds. Can still access Realms. Error message “Guardian” with the text: “Your discovery environment does not match the host's.”
