This is critical bug that makes default or Standard skinpack doesnt work for multiplayer (Tested on server, world, and realm with 2 devices) With this bug, you can only use skin that came from persone skinpack. So if you use "Steve" and "Alex" that's from default skinpack, the skin is just invisible as you can in the video below :

Thank you for your report!
Your report is a little difficult to understand. For example, there is no "default or Standard skinpack". You probably just mean the Steve and Alex skins, which are built into the Character Creator, but in your video you haven't created any characters (your 5 character slots are all empty), which doesn't seem normal to me. So I'm not sure what you've done to try and create your skins.
However, from the video I can tell see that you're experiencing a very common bug that affects multiplayer worlds. It causes skins to get mixed up—players have each other's skins, multiple players have the same skin, and different players see different skins on the same third player. We're already tracking this issue at MCPE-48207, so I will resolve and link this ticket as a duplicate.
