Been using the app for more than 5 years. Used Apple Watch Series 3, series 7 and Ultra 2 for my training records. Noticed that my best records for running were not accurate. Specifically the app showed a badge with time for best running records (5k, 10k & HM). The times shown on the badges were shorter than the actual time recorded. Moreover, after I switched to AW ultra 2. Some of the running records including longest runs went missing. And my best times shown on the badges were close to world records.
