I have used the MyAir app for the past seven years but all of a sudden it quit working. I have tried reinstalling turning on and off etc. but the indicator on the CPAP shows that it is not connecting with telephone service. When I talk to the local vendor for resmed they said they had lots of complaints recently and think it has something to do with the switching of phone service but nobody could help me. I am really hoping sleepyhead works for me. Thanks
