I haven’t been able to open the app since the last update. First got the error message that the feed couldn’t load and was asked to reload or reset. Neither worked so I uninstalled the app and reinstalled and now I’m back to the failed authentication error message.

Same for me. I think mine is related to I had changed my PDS a few weeks back and was not loading before the newest release. Now it close as soon as I open on iOS

Same for me, but I’ll add that I deleted the app to make sure the data cleared in an attempt to get it working
