Since the last app update, it seems I have a 50/50 chance of the events tab loading properly. When it fails, I select the camera group I want to review, but it will only show the last group selected(from the previous session/day when reviewed) Sometimes I am able to reboot my phone and it will work, but now often it will not. Is this a known bug already?
Welcome to the Forum, @seankelley71! 
I wonder if you’re experiencing an issue recently described in another topic:
I haven’t experienced this myself, but I don’t frequently use the Events tab in the app.
Yes. That other topic describes a similar problem, that is, events only showing from the previous day (and other days prior).
