Version 2.1 has serious bugs

I’ve used this app for years and I loved it. Among other things you can text via internet with no cell reception. But about a week ago, m phone became totally unresponsive and kept getting worse. Finally I looked at battery usage and, despite not using the app, Google Voice was using 43% of my battery just churning in the background. I uninstalled the app, rebooted my phone twice and zoom! Was back to it’s old quick self. Hoping it was a bad install of a good app, a day later, I reinstalled it. Even though I never even signed into my account, a day later my phone was sluggish and unresponsive. I once again uninstalled and rebooted and zoom. My phone is bright and peppy again. Conclusion: do NOT upgrade to Google Voice until version 2.2 comes out. This, by the way, is on an iPhone 5s
