achievements not working after game crashed.... tried to enter the nether on my realm and the game crashed. after the crash cant complete any achievements in my realms or a creative world

I'm playing a survival realm. I had build a nether portal. As soon as I tried to enter the nether my game crashed. Killed the app from the background and started the game again. It crashed a few time then started. I was playing as normal until I realized I never got the achievement for entering the nether. So I tried to get the achievement for connecting chests to hoppers to furnace and nothing. I tried to sign in on my iPad and same thing, even tried to create a creative world and cheated and nothing. Still no achievements. I noticed I was able to get one while playing on my friend realm but not on my realm nor a created world on my iPhone or iPad
