I'm having a big problem with my MCPE, I had an iPhone 5s and played Minecraft on it, I always had a problem with the delay of achievements, it took 20 seconds to 2 minutes to appear, I changed my phone to an iPhone 7 and the same error continued, everything was fine, there was only a short period of time for the achievements to arrive, however, since yesterday the achievements no longer appear, I got 2 but they did not appear, the achievements of catching the breath of the Ender Dragon and the achievement of reviving the Ender Dragon, I DO NOT use cheats in my world and since yesterday they have not appeared, I tried to accomplish another achievement in another world, the achievement of spending 2 or 5 minutes under the water, I do not remember right, however, she did not appear too, I tried to leave and enter my account but it didn’t help, my nickname is Hazzard3003 but previously it was DaniJoao, I don’t think that the nickname change has caused this error, my Minecraft is original, fix it please.
