This is an exceptionally frustrating error because if you have set the "Today in History" tab as the first tab in your list, like I did, you will be completely unable to use the app.
The error is the only thing you will see when you open the app, with no other UI elements available. This can only be resolved by clearing the app data completely and re-ordering the tabs.
But generally this error in "Today in History" is still happening (android) and has been the case for the last few days.
