Notifications on Andorid broken



I'm using Seeking Alpha for more than a year now and since then the notifications on Andorid are broken. In at least 20% of the cases I end up on a white screen when clicking on a notification. The only solution here is to terminate the app and try to find the news/analysis by browsing, as the notification is now "consumed". 

That's very tedious if not to say annyoing, especially when taking into account that this is a pretty high paid app with the yearly subscriiption. Could that please be fixed?
