Same in 1.14 (Bee update) - Tested today.
Something else I have tested this morning (as I thought it was due to my childrens accounts) I have tried it with an unrestricted account that does not have xbox live if that helps 🙂
I have cleared out all the local data for minecraft on the xbox and re tested and this issue is still happening.
I have also performed a fresh install of the game and nothing has changed.
I cannot access the log file on the xbox - otherwise I would add them to the issue.
I have exactly the same issue in 1.13.2 on the xbox one - however in my case I am using a pc to lan play with the xbox
I can confirm that this is still happening as of 3rd June 24 on bedrock-server-1.20.81.01 - with a freshly generated map - occurs every 2 minutes.
It doesn't effect play but is noticeable - I attached the log
