When will OFDMA scrambling of 5G be corrected for RAX42?

I'm not a patient reader to muddle though all OFDMA topics so I'll make mine new and simple.

When I enable 5G OFDMA on my RAX42, all heck breaks loose if multiple devices (even just two) connect at the same time.  The 5G network locks and no device can make a connection.  It requires a router reboot to clear the issue and then one, and only one, device logging on to disable OFDMA before stability can be had again.

I'm posting this at least TWO YEARS since the same topic had been raised in a discussion thread that was shut down (replies locked out like its not a topic to be spoken of anymore (my interpretation on seeing the lock out.)

My router says its firmware is up-to-date.  So, am I missing a fix (or just confirmation that OFDMA is not advisable for 5G) or is this a 'glitch' in old hardware like mine that requires a new purchase to correct?  For now, I don't have many devices connected so my fix is to just leave it turned off.  However, someday, a high device count may become a reality so I'd like to know how to plan for it.
