Today I have charged my Forerunner 235 on my laptop, something which I normally do. Some time after wearing it I noticed that the time that was showing was totally incorrect. I changed it to the correct time, and after some time I found it once more incorrect. Then I re-corrected it again and switch off the auto-synchronization function. I tried switching it on again later but noticed that the information from the watch was not showing on the app in spite of the fact that it was stating that it was syncing. Maybe someone could help out since it seems that I will have to set the time manually and refrain from synching it with the app and that makes the watch almost useless.
