My FR645M keeps dropping apps.
I don't know when this happens but it happens almost every day, sometimes even multiple times.
It seems to happen at different hours so probably not related to time reset or anything.
When this happens, all the installed apps will disappear from the watch but the music will not.
Usually I only install the Forerunner 645 watch face, datarun (data field) and all-in-one (data field).
It is very annoying.
Anyone has any ideas? Thanks!
