They made it crap a long time ago. The app takes forever to connect and view the camera. Really feels like abandonware, except for the ads to push you to buy more of their cameras or subscribe to their service. I’ve just cancelled my subscription. Moved to Tapo cameras, where the app connects nearly instantly… for now.
I don’t use a hearing aid (…yet), but I do find videos difficult when the audio mix has the ‘background’ music too loud relative to the voice.
