The App TP-Link Omada, which I downloaded and installed on my iPhone 6s+ from the App Store makes unneccesarry changed to Omada Controller settings.

On my Omada Controller, I set WLAN Schedule on some of my Wireless Networks. I also set Rate Limit (Download Limit/Upload Limit). 
Now, when I try to make changes from the App, changing/updating rate limit for example, the moment I saved the changes, WLAN Schedule is also disabled. It doesn't just save the changes on Rate Limit, it also disables other features enabled.

I don't know if there are other settings that is messed up from this app, but I've only noticed WLAN Schedule disabling since I was using this feature. WLAN Scheduling can't be enabled or disabled from the App, no option to modify it, but App automatically disables this feature everything you make changes on the Wireless Network.

So for now, while this bug exist, I only use the App for viewing purposes. I don't want the app to disable services/features on it's own without me knowing.

Update:
MAC Filter as well is disabled after saving changes from the App.
