There seems to be no specific place to leave feedback and bug reporting via Play store app anymore. Usually click on Report Feedback to Developer directly in play store beta app page.
I've tried everything I can think of,... Delete Cache, Delete Storage, uninstall reinstall, but nothing has worked. Even tried removing and re dding accounts. I keep receiving "Error Communicating With Servers" error message with all of my Authenticator accounts and then it re display the screen to select number and accept.
