Phone App problem

Motley sends notifications to my phone maybe a dozen or more times per day. I can no longer open them. i click on them, it sends me straight to the home page on the app and the article never pops up. and then the notification is gone and i miss the article i wanted to read. 3 days this has been going on and Motley does not respond to my inquiry about it. i have already rebooted the phone, to no avail. help
