You kind of make your own stability (eg foregoing app & firmware updates if things are working well) and uniformity (eg using a single cam model to avoid all the variations across models in the app UI.)
I think there’s discernible improvement in the former * though not so much in the latter. We’ll see.
* I’m running the latest firmware on all cams (v2 v3 OG) and devices (bulbs and plugs) and the latest app (v3.xx) which I didn’t do until about a year ago, so that says something.
I don’t auto-update, howver. Like @StevenA I monitor forum threads for each release to see if its ‘safe.’ And only then install on each device individually, not in bulk.
