Messenger for All Message Apps

This app the worst messaging app I think I have ever used. I missed very important texts because it failed to notify me. And it sure didnt combine all my messages into one spot. t shouldn't be that complicated. I really don't understand why anyone would want a messaging app other than the one that comes with the phone or the social media sites.

The worst app ever. It continues to take over my other apps with bombarding me with ads while im using other apps . I hate this app. It was ok as a secondary messg system. Once I intalled the messenger home app, disaster happened. It took over and will not stop trying to be my default messg system. I gave up and let it be that system of default it bombarded me with ads I couldnt keep up with clicking no on the ads ..I hit x after x after x after x and more ads would come to the point I lost

Since recent update its like a virus it wants me to set messenger as the default and there's this red block on the top and I try to do it but it won't even let me do it and there's ads everywhere it's horrible. I can't even get to where I set as default, it just wants me to install a apps I don't want with no way to dismiss. It's a virus
