That sounds like misconfiguration. On my network, both bands connect to the same subnet so traffic between them is seamless. I can't speak to how random makers of IOT devices configure their systems 🙂
I'm still struggling to understand how having 2 bands available should cause problems. If they don't want to use 5 GHz, they should ignore it. I sometimes wonder about the competence of some companies. Someone else mentioned TP-Link access points. I had one of those and found it leaked multicasts from the main LAN to the guest VLAN. This made it impossible for me to use IPv6 on my guest WiFi, as guests would wind up with addresses from my main LAN. When I called support, they tried to claim that was how VLANs are supposed to work. It was only when I talked to 2nd level support that they recognized that as a problem. However, there was no fix forthcoming, though I believe it has been corrected in a later version. I fixed it by replacing the TP-Link AP with a Unify AC Lite, which works fine. That problem also existed with some TP-Link switches.
