I'm with @alemabrahao . I have had issues with 2.4Ghz only clients (especially IoT devices) that are unable to see the SSID when band steering is enabled (it prevents them from connecting to WiFi all together). I have gotten sick of dealing with these edge cases, so I rarely use band steering now.
Meraki's documentation specially calls out this issue:
https://documentation.meraki.com/MR/Radio_Settings/Band_Steering
"When band steering is enabled on an SSID, APs will stop advertising that SSID in 2.4 GHz beacons. Since 2.4 GHz-only clients that rely on a passive scan will not “see” that SSID in beacons, they might not be able to join this SSID unless they do an active scan or have been pre-configured with the SSID name and security settings (for example, a pre-shared key)."
