Zero Stars: Unusable/Major Perf Issues

I dont write app reviews, but Im so frustrated by this big bang version I feel I must weigh in. A Material Design skin does not an app make! Although I disliked the pre-Marerial version for its rather sad user interface and that it was essentially neglected for years, the new version is utterly UNUSABLE. It is plagued with usability, functional and performance issues. Was this even tested on device(s)? I even restored my iPhone 5s to factory settings to make sure it wasnt my hardware. It was not. Whats really sad is that an engineering driven company such as Google let this go out. Im seeking an alternative for my Google voice number. Apple ignoring hardware, Google ignoring software. Whats next? For all the growth UX/Product design has seen, most apps/platforms are still essentially user rage factories. Do better!
