The most recent update of MyDlink app (3.8.0), dated 18 July 2017, on my iPad Air with iOS 10.3.3 is always crashing on startup. Is there a fix coming soon? My camera is not a toy! Please fix!
I can only offer this advice which worked for me previously on Android when I had something that resembled this.
Uninstall the app. Delete it. Then install from the store.
Please report back if this works.
