The arms of my skin keeps resetting everytime I enter Minecraft. I choose the slim type and it resets to default, but that isn't the only issue. My skin is also not visible to others in multiplayer. Instead of my skin, one of the free bedrock skins appears (not Steve or Alex). The "Only Allow Trusted Skins" is turned off. I don't know if these issues are connected, I tried to resolve them both, but to no avail.

Things I tried: Checking the skin file format, restarting game, restarting phone, signing out of my Microsoft account, cleaning the cache. None of these worked. 

Here I will include a video and a screenshot of what my friend sees when we play together.

Ps: I saw someone posting this issue and saying it was resolved, but it didn't tell how to resolve the issue so here I am.
