Thank you Friedl! I did see in other threads in this community (here and here) that there are definitely cases of SSIDs having the same name which allows for the initial connection, but then the router will force the Photon to the 5G which will cause the disconnect. I am still waiting to hear back from my customer if that’s the case with their setup, but I strongly suspect this applies to my situation as well. Will update when I find out!
