Hi it finally solved i dont know why it happened but i tried to evolve it again like 3 or 4 levels more and later it evolved. It should be a ocasional bug in that moment or something. Sorry for dont take out the post when it solved but i didnt know how. Thank you for your answer

Hi everyone: So i wanted to evolve my eevee to umbreon and the evolving screen appeared and i pressed yes and the game said that i had umbreon but i still have an eevee. Why is this happening?
