H9 Control both on iOS and the desktop doesn't save any information about the state of the pedals locally. When you open up H9 Control on iOS or the desktop and go to MIDI program change mappings for example, it asks the H9 for information about its MIDI program change mappings and it shows you what it received from the H9. That's why sometimes a spinning wheel pops up briefly when you go into a new settings page; it's still waiting on a response from the H9. So, if you change anything on the H9 directly or on the app on one platform, you should see your changes in the app on another platform.
There are a couple of possible explanations for the behavior you were describing. One, possibility is when H9 Control is launched and no device is connected, it goes into demo mode, and then, the values it shows you are dummy values because it's talking to a mock H9. So, it could be that you were in demo mode one of those times; in the titlebar of the app, it will tell you if it's in demo mode or is connected to an H9. Another possibility is that your changes weren't saving for some reason. We have seen that happen sporadically when editing values directly on the H9 in its setting menu; I can't recall ever seeing that happen when using the app, but let me know if you think that's what might have happened.
