I have Google discover set as my swipe left from the home screen. Below you can see google discover before and after the beta. I am missing the search bar, weather, voice search, and Google lens buttons. Unless I am missing a setting somewhere these are just gone now. Please add these buttons back in as I use them quite frequently.
I just cleared data as instructed with no change. Additionally I cleared the cache of the Google app and restarted the phone. The swipe to the left of the home screen Google discover is still missing the previously mentioned buttons. Curiously, if I open the Google app, Google discover is displayed properly. So it is an issue only affecting the home screen (launcher) version of Google discover.
