Rax80 smart connect issue wifi dropping

I just upgraded to this router today and updated the firmware to the newest V1.0.1.62_1.0.26 and I am having the same issues with smart connect. When I first booted up the router and connected to it with my phone it was crushing speed tests. Then I decided to enable smartconnect because I had been using a two network setup and thought what the heck. Immediately my phone started dropping connectivity very frequently and all the devices on my network were locked to 2.4ghz. Speed was obviously affected along with the connectivity. My phone would barely make it a couple minutes without a webpage not loading and me having to refresh it for 10-15 seconds until it reconnected. I couldn't even barely log into the nighthawk app to turn smart connect off because it kept disconnecting on the app. Anyway I disabled it and it has been working flawlessly on all devices. Also all the devices that were locked on 2.4 are now on 5ghz except one smart home device that is 2.4. Thought I would share since this seems to be an issue with this firmware.
