my skin character get's being set to default

Hello. So I bought Minecraft Bedrock on my phone recently after playing Java and Bedrock for many years on PC and Bedrock on Switch for a few years

everything was working fine until I got my copy on my Android Samsung Galaxy s21 and I keep getting this pop up (attached image) where it explains how skins works and then it somehow manage to set my current using skin into a default one (like Steve, Alex and the others) 

so if this could be fixed, I would appreciate it a lot! thank you!
