Orbi AC2200 Tri Band RBR-40 w/2 RBS20's

I have the Orbi AC2200 Tri Band Mesh system with 2 RBS20's. I had an older nighthawk router before this. I had no issues with the nighthawk but wanted to upgrade and extend my wifi range with the mesh system since we built a barn which is right beside the house. Since switching, our wifi is actually worse. We no longer have wifi in our garage or on our back porch with the mesh system however with the older nighthawk we had internet all over our house and outside on our porches and even all the way to our gate. I'm wondering if it is the mesh system, or is it in how I have it setup? The wifi connections are now very spotty and in/out, not as extended as they were with just my nighthawk router, and really I feel as though I wasted $350 on a system that doesn't work and I can no longer take back since I'm past my return period. I have chatted with support through the iPhone app and did troubleshoot but nothing changed. Does anyone have any suggestions? Reviews I have read say this system should give me service in my barn, but I can't even get service from one room to the next even if I'm sitting right beside one of the satellites. Right now my MacBook is connected to the main RBR40 even though it is literally sitting 1 inch away from a RBS20. Same thing with our phones, they won't connect to the different satellites or router as you move through the house. They stay connected to just one. It's like the system is not "meshing". They're each acting as stand alone wifi units but devices pick and choose which one they want to connect with even though they aren't connecting to the closest one. I greatly appreciate any help or advice in trying to get this system up and running correctly or if you know if I can send it back to Netgear for something else. I'm ready to unplug this and go back to my old nighthawk that was working better than this upgraded system. Thanks!
