I've paid subscription for yrs & w/no issues, but within the last week, I'm no longer able 2 assign or change ringtones 2 my phone and am now missing important calls & messages because I'm not getting sounds for 1/2 of what I had tones 4, just quit working & can't change 'em 2 anything else. If this isn't fixed soon, I'm going to have to switch to a different app. I work in mgmt with developmentally disabled individuals & have several staff. Can't keep missing time sensitive calls/notifications.
