I don’t think this is accurate, and I’ve never seen documentation to this effect. If the Reset Services actually did this to camera settings, then I think a lot of unhappy customers would be kvetching a lot more about all of the reconfiguring they have to do each time they exercise this option.
I think you misunderstand what the Reset Services button is intended to do. You can tap the beside the setting label for a brief description of what the button does.
Although the Help Center article describes it as a feature available to Cam Unlimited subscribers, I’ve also seen its use described as part of a solution to the issue of certain cameras failing microSD card playback from events.
You may have moved the slider for one camera without realizing it, or I suppose it’s possible that there’s been a miscommunication between your app and Wyze’s servers and/or you have some glitchy data in your profile. Even deleting the app’s cache/data and logging back in shouldn’t blow away your camera settings (nor reset them to defaults), and that would be one way to grab a fresh copy of your data/profile from Wyze’s cloud. Just don’t ask me how to do that on iOS.
