We reported this when the problem came out. Years later they still haven't fixed this and what I was seeing on the Ubiquiti forums (before they broke them) was that they were very uninterested in 900 Mhz improvements.
My limited experience with old Motorola/Cambium 900 Mhz wasn't that good either. But I have to use Rocket M9s for a link to my house and it's functional with old firmware. But it could be better.
