I downloaded my first raining plan into the calendar in my Samsung Galaxy S6 phone. All well and good. Somehow, though, I’ve managed to duplicate it, i.e., I now have two of the same session showing for every training day for that plan’s duration. How do I eliminate one of the plans? Also, how do I shift a session from the default day, let’s say Thursday, to another day, say Friday? This would also have to be done on the Samsung Galaxy S6.
