If you have recently updated to iOS 12, accompanying the update for the Apple Watch that has come hand in hand, you may have realized that some awards or achievements may have disappeared of which we are achieving, meeting the objectives and which for many are of the utmost importance.
effectively Apple knows perfectly well that some Activity awards have disappeared, but promises that they will return in a future update. This is a strange move by the Cupertino company and given the failures of watchOS many users feared they had lost all their prizes.
Apparently they have officially confirmed through a document uploaded to the support portal and development that it is a known error and that it will last a while in the operating system, although knowing that both watchOS and iOS 12 are already in the next beta phase, so we understand that Apple is working and a lot on polishing these last details. The trophies that seem to have been lost: Thanksgiving Challenge 2016; 2017 Mother's Day Challenge; Veterans Day Challenge 2017, Thanksgiving Challenge 2017; National Sports Day (China) 2018.
Some of these challenges are specific to certain geographic regions, or on the other hand, you may not even know when they were available, but it is still a mistake that has worried those who took their time and especially their effort to achieve the aforementioned challenges. If a challenge has disappeared for you, don't worry, they will return with a next iOS update, so patience is going to be one more element in our relationship with Apple these days. So, a problem more solved or at least on the way.
