Just today I load my app(s) (android and/ot IOs) and noticed the Room Names are no longer in order in which they were initially arranged. Re-arranging the order is not that difficult but is this yet another of the many daily tasks required to keep ST devices/apps up and running??
Not seeing it; mine have never budged. Is it possible you have another friend or family member with account access (e.g., for presence sensing)? Any reorder done by anyone with account access will be visible to all users of the account.
One user. Me 
Mine did the exact same thing…
