Wow, thank you, that is amazing news. Can I ask how you found this fix? I turned up nothing after scouring reddit on this one for a long time.
EDIT: just checked, my router doesn't even support WPA3... I think it's typically the 5GHz network that upsets it, but I suppose I'll just continue resetting it for now.
It's on 5ghz on my end, and switching the UniFi lite AC to WPA2 from WPA2/3 fixed it.
The thing is that the 2.4ghz wifi from the S90C (they both need to be on the same network for some goddamn reason to work in SmartThings) interferes with my DualSense gamepad.
Because I want to listen to Tidal on full quality and control playback via my phone. Bluetooth quality is garbage.
I don't want to turn on my TV to listen to music (and Tizen only allows up to a certain quality), or use my nvidia shield, as it also turns on the TV via CEC.
Other platforms also don't support full quality like FLAC or Atmos mixes.
