Cannot change custom skins in-game.

I play Minecraft PE on IPhone 8+. When update 1.7.0 was released, there is a issue with changing skins in-game. I go to change my skin, I click choose new skin and I choose the skin I want hen it ops up the choose the correct skin model however the skin I choose from my photos is not showing and it shows the skin I had on before I picked a new skin to have on in the choose correct skin model pop up and even after I clicked the skin model and clicked confirm the skin doesn’t change it’s still the skin I had on before this also happens when I’m in a world I go to change my skin I pick the skin I want to use and when the choose correct skin model pops up it still doesn’t change even when I chose the correct model and click confirm nothing happens the only way I have found to change custom skins is when you change your skin and it’s still the same skin I had on before I have to reload Minecraft and when I do the skin I want On is now there and not the one before please fix this this is also happening to other people and I do not want to have to reload Minecraft every fun just so my skin that I changed to can load I hope I explained everything clearly if you need more information I can send a video containing what happens and send it to you thank you for understanding.
