In Bedrock (Realm), I have a functioning Ender Pearl Stasis Chamber to allow teleporting home. I have it built correctly with honey and the bubble column with trapdoor.

It seems to function fine on a short term basis- However it failed when I wanted to teleport my friend home after an adventure.

Is there some condition upon which Ender Pearls lose their data? Is there a way I can ensure this won’t fail?

Thank you for your help.
