This app has been going downhill since I last installed it. The campaigns say application or system error. Tried it with a computer like they asked me too but that didn't improve it at all.
I'm so sorry you had a experience with our app. You never really told us what was the problem you were experiencing specifically and so we were not able to address your issue properly. That being said, the app is made to be used on desktop and it also depends on what browser you are using. If you feel like giving it a try again I can offer you the Pro plan at a extremely discounted price so you can further experience it.
