Workaround I ran across elsewhere in forum - use the share function (select the exercise, click the share icon, click the exercise icon) and select the exercise from the resulting list - you get a graph that is similar to the graph before the dubious app "upgrade" that shows average bpm and max bpm. You don't have to actually share anything if you don't want to. Makes it even more maddening that they won't just put this graph back on the exercise tile - obviously everything needed to put this graph on the exercise tile exists!
