Connecting Orbi to iAquaLink pool system

I have pretty much the same situation except my Iaqualink worked perfect for about 2 months, then all of a sudden as soon as I would try to open the app or login, it would get kicked off the network.  Iaqualink feels there's something about the mesh system that it tries to push 5ghz onto products that only accept 2.4 but that doesn't jive with the fact that accessing the app is the process that kicks it off the network.

Jandy (owner of Iaqualink) sent their rep here, he  replaced the chip and the antenna, no change, we checked the settings to find that my orbi was inadvertantly set to auto on 2.4 so I changed it to channel 1.....no fix. The signal is full strength at the antenna as I am only able to get 25mb/s wifi here and it's full strength thanks to the Orbi, but whatever causes this handshake issue is unknown.

As a 2nd to last resort I have turned my uverse 2.4 wifi back on (left the 5ghz off) and re-set the antenna to connect to the att uverse, even at a whopping 1mb/s it's working and has not kicked me out.

To recap:  The Antenna will connnect to the orbi router and hold it's connection UNTIL you access the app and try to use it, THEN it kicks the connection (for me this is what is happening) I understand some of you aren't even able to get connected in the first place which is also strange)
