Did iOS 8.4 break Google Hangouts calling over WIFI to any landline or cell number for anyone else? I now get "invalid number" for any number I attempt to dial which was working in 8.3. Tried uninstalling and reinstalling app but same issue. Next step is reverting back to iOS 8.3 before Apple stops signing it. I use this on iPad without cellular to have calling capability over WIFI. Does Apple do this on purpose because I can't imagine them not QA testing a high profile and essential app?
