For years, Mobile, Switch, and Playstation have had different loot from Xbox/PC. This was caused by the code for the unpacking of loot-tables being different (as better explained in MCPE-161133). This resulted in every seed having different and sometimes “better” loot on Xbox/PC while other platforms got the shorter end of the stick. However, in version 26.20 this issue was fixed but resulted in Xbox/PC getting the worse loot that the other platforms have been dealing with where it should be the other way around, with Mobile/Switch/Playstation having the same loot that Xbox/PC had prior to version 26.20.
Here, I have attached images of the contents of a Buried Treasure on Seed: -541714255396397480 located at coordinates 280 60 1240
The one image shows the contents of the Buried Treasure on PC on Preview Version 1.21.130.20 (as shown on the top of the image), Note how every slot has an item in it and contains a spear. The other image also taken on PC shows the new contents of the same Buried Treasure on 26.20, now with less items and spear-less. The last image shows the contents of the same Buried Treasure taken on my Phone, Note how the loot is the same as the new PC loot.
If more proof of this phenomenon happening with other loot chests or seeds is needed, I will be happy to provide.
Expected result: Mobile, Switch, and Playstation share the same loot that Xbox/PC had prior to the 26.20 update
Actual result: Xbox/PC now use the loot that Mobile, Switch, and Playstation in update 26.20
