Every time I close my TomTom Sports App on my Android Phone then reopen the app and resync the Adventurer watch, the clock resets to the 24 hour clock. I have to go in and reset the watch back to the 12 hour clock. This is annoying to have to do this several times per day. Does anyone know how to remedy this? The user manual just tells how to set the watch to either 24 hour or 12 hour clock.
