My phone is Samsung A71 5G. I installed Dreammapper app and logged in successfully, but the app was unable to pair with phone. I tried unsuccessfully with both DreamStation and new DreamStation 2. A relative has a ResMed CPAP and the the accompanying app works perfectly. The ResMed app beautifully displays usage and AHI data. Why can't Philips get their app to work too? There are so many dissatisfied reviews. I do not understand how others were able to pair their phones.
