The amalgamated Harmony Software tends to be unstable for new products like the "1000" and the "One" (teething phase), but quite stable for older products (like my 659 and 680). This is compounded when you create workaround(s) "outside the box". The last time I had a major upheaval with my 659/680 is when Harmony Software replaced the activity device columns by a single device column. I had to redo my activity clone technique single key macros, with the new activity sequence feature.
