With all due respect, “heard” from whom? And are you now that person who the next person “hears” this from?
Given that the clients are in full control of their behaviour, I will share that DAWN is working very well in my setup of 4 APs. Both FT (for clients that support it) and 4WAY (for those that don’t).
There’s no magic configuration for all users. You will have to read, adjust configuration AND (lower) power across devices to reduce overlap and help transition.
The DAWN thread may be a better place for you to ask for help after reading the DAWN configuration guide and adjusting your power etc.
